  1. I use to buy chinese instruments for several years from our chinese supplier. At the beginning, everything was quite perfect, but lately the origin of the instruments seems to have changed, and the quality also. I had problems of cracks appearing on the instruments stored in careful conditions. If I buy these instruments, it's because I like them in the first place, and that we have clients for it. Usually I would strongly defend chinese instruments in general, but on this particular aspect, I won't invent another origin just to do so. A thousand thanks to you all for your advices, this site is definitely great! Mat.
  2. I think I have what I need! Thank you so much for your help and precious advices. Mat.
  3. To reply to your question, we set-up chinese instruments, and restore antique violins. The cellos have been stored for 6 months in their cartons, with normal hygrometry and temperature conditions. On the contrary, I find your answers very instructive, and it confirms mainly what I thought (regarding the fact that the woods were are unsufficiently dried, and that the ideal solution would be to open the cellos and cut the ribs, which is not very interesting for these instruments indeed). On one cello, the lower rib joint was out on a big section (say 30 cm), I tried to replace it manually, clamping and gluing progressively, it is closed but the seam is not regular, it is lower near the bottom block. On all the other cellos which have this problem, the opened section of joint is much shorter (between 5 and 10 cm). It would be a pity to throw these cellos away! It's quite impossible to do alone indeed, but the 4 hands solution is not entirely satisfying, as it's very hard to have a regular pressure. If a lateral clamp could do the job for me with a more regular pressure, it would be great. I found another one on the Howard Core web site, but it is for violins also I think : http://www.howardcore.com/cgi-bin/shopper....&key=735605 If anyone has heard about this for cellos, I would love it. Thank you all for your advices. Mat.
  4. I own a little workshop, and we have some problems with some of our new chinese cellos. The quality of the glue seems not to have been perfect, and the ribs began to unglue on several instruments, some on top ribs, some on bottom ribs. It would have been nothing, but we didn't notice it immediately as the cellos were packed, and unfortunately the ribs have been pushed out of their normal place. It's then impossible to glue it again without pushing the ribs back in place. Unfortunately, I don't know how to do this. I have seen a tool for this, but it was for violins. Would you know where I could find the appropriate tool, or would you have an advice? Thank you for your help! Mat.
  5. Looks like a good south german / austrian viola from 1890/1910 to me, but of course it's just an opinion.
  6. Another advice...actually I didn't see any violins from 1850 with this kind od wear near the f holes, the front looks like typical 18th century wear, but maybe I'm wrong. And I have not in mind 1850's french factory instruments with this type of making...I am wondering if it could be a french provincial maker around 1780/1800.
  7. It's interesting, I did not explore this possibilities : could you tell me which characteristics let you think about it ?
  8. Hello gentlemen, I bought recently an old 18th century violin ( I guess it is ) with an apocryphal " Alessandrus d'Espine" label, and I'd like to know your advice on it. It doesn't look german, the body is flat, the head is finely carved, and the violin is Stradivari style, 357 mm. Could it be french or italian ? any idea of makers with relative works ?

  9. I really see a difference between selling chinese violins without yelling around the origin ( because chinese violins still do not have the reputation their craftmanship deserves ), without labels, and selling chinese violins with a FAKE italian label, pretending you ignored the origin even if YOU have put the labels into the violins you perfectly knew as chinese ones. Here is the difference : in the first case you're trying to sell chinese violins for the quite good instruments they are, in the second one you are a cheater. By the way, chinese instruments are handmade too ;-). I agree with the bad salaries and work conditions in China - even if a personal embargo on chinese violins would certainly not help them -, and I think european and american violinmakers have to focus on the high level production - the chinese are unbeatable for copying, not always for innovating and being unique...mass production cannot have every benefit. But caveat emptor, as you said.
  10. Longrifles, the complaint is not about buying chinese violins ( which are often a good quality and workmanship ), but about buying chinese violins from a seller pretending them to be italian ones ! that's the point, the chinese violins are fine and nicely carved, and detecting differences becomes hard for a non-specialist, who thinks he gets a bargain ! this seller is a liar, that's all, and his account should be shut by Ebay, that's my opinion.
  11. Thank you Kolovrat, actually my question was not "how to avoid this kind of seller" - I wouldn't have the idea to buy an instrument from him thinking I would buy an italian one - but "how to inform the Ebay community and new buyers about this kind of seller". Anyway, I didn't know professional sellers were using public great auctions to sell the instruments they couldn't sell otherwise, that's a great information and it sounds logical, afterwards.
  12. Hello, I'd like to have your opinion about "violinkid" on Ebay, because I see for a long time now he's selling ( chinese ? ) violins and bows under fake labels and brands. The violins are branded with fake marks and labels ( Gaetano Gadda on 19th century german violins, Carlo Tramonti on chinese ones ), and the bows are signed with french or german bow makers names. Then he sold for about USD 3500 a 19th century german violin which could worth around 500 with a "GG" brand...which makes about 700% benefit. Don't we have any possibility to prevent buyers from this type of lies ? I did not buy from him, of course, but it's not very fair for people who cannot make the difference between an original gadda and fakes...what's your opinion ? http://search.ebay.com/_W0QQsassZviolinkidQQhtZ-1 Kovaltchev
  13. Thank you Fiddlecollector, I hope the label is authentic : )
  14. Thank you Michael, at least you confirm my impression it's a french violin. Regarding the certificates, I don't know if it's a 100% method, as a violin maker can really change the characteristics of its own production among years...then, even with an original labelled example, a mistake would be still possible. The better way I think would be an original violin + detailed pictures of the others...which is certainly very much to ask :-). I use Tarisio for the pictures, do you know other web sites ? maybe Christie's or Sotheby's catalogs are helpful too ?
