  1. I operate in Celsius… kept it under 100, maybe 80. Still had some thin gloves on handling it while warm. I suppose you can try hotter and shorter or cooler and longer. The objective is just to “dry” the wood core and make it shrink a tiny bit.
  2. I find rings come lose and tighten again with the seasons as the wood core expands and contracts. Sometimes I just wait for the weather to dry/warm up before I attempt to realign or take off and refit a misaligned ring. I have had good success baking the adjuster for a couple of hours on very low heat in the oven if I don’t want to wait for summer.
  3. Can anything be said about when and/or where metric bow screws were used?
  4. My favourite bow of 40 years I dropped and broke the head off 30 years ago. Was repaired and played ever since with no difference at all. While it lost 80% of its resale value, utility has remained unchanged. To acquire such a bow would seem a great bargain and for the same reason I would never sell it. But maybe I’m just lucky or oblivious to the risk of future failure. As an economist by trade I will say that there must be a reasonable reason for the typical devaluation. No free lunches anywhere.
  5. Got my own box with this designation, in which this bow has lived for an unknown number of years. Just thought the head looks somewhat interesting…
  6. I guess it's an old German bow, but I can't tell if it is indeed rather early (e.g. from the Knopf woods), or a later so inspired version. The head has a curious shape and rather broad cambers - might ring a bell somewhere? Any opportunity to learn appreciated.
  7. Actually looks more like casein formaldehyde (6), but I still don't discount horn (1) based on the tiny sample in this study. Might be good to know if any of these are not suitable for bow frogs (e.g. strength), or what was actually mostly used for frogs and reasonably available to bow manufacturers at various times.
  8. Thanks. Now I know it's neither tortoise shell nor plastic; but could still be made from horn, cheese or wood. The tinsel is probably a radioactive.
  9. Any ideas regarding this bow appreciated. Note the adjuster is very likely a replacement. The pearl slide backing of rosewood is done quite neatly and as far as I have seen somewhat unusual with the rounded end. Maybe this can give a pointer?
  10. ... had a quick look: the ebay specials of the day ($25 and up) all claim to be made of ox horn. Maybe frogs in horn look were always real and never made of plastic?
  11. Old(ish) bow with tombac mounts. I think it would pre-date good enough plastic but could be wrong. Is this most likely horn? Are the cheap new Chinese ones of this look now plastic or still horn?
  12. Hit and miss. I have bought cheap stuff from China that turned out a useful budget alternative on student violins; as well as stuff that went straight from the package into the bin.
  13. I have got a couple of bows stamped GDR, and that was my first thought too, but it doesn't seem to match very well. Some of the visible lines do not fit/ form part of the alleged letters. I thought it could read BRD (which is the German acronym for FRG), but that would be odd in conjunction with the English "MADE IN..."
  14. And a little more oddity with this adjuster: it doesn't seem constructed in the typical way with an ebony core and two rings. Or maybe it is except the lower ring is more like a cap with integrated nipple recess.
  15. Thanks for the name of it... and all the info that google turns up for it.
  16. This is an extreme case of nail damage - it is unusually deep. It can and should be filled by a competent bow restorer.
  17. This blonde bow is stamped on the butt end to have originated from a three letter acronym. What is visible of those letters does not match any of the usual suspects for me. Any ideas?
  18. Yes, flat, or rather square. Wide spaced, too, and at quite an angle (giving lots of movement per turn). Have you seen it before?
  19. The bow looks cheap and new(ish). I guess someone who shouldn't replace faces has done so on this bow. Get your first violin first, acquire some experience, then look for a bow. Ebay is a trash dump for the most part, be aware.
  20. This Mirecourt bow has a rather strange adjuster on it, which may be a replacement, not sure. Anyone seen anything like it? The metal has behaved/ oxidised rather differently from the nickel mounts on the frog. From a distance it looks more like aluminium, but it has the proper weight (4.3g). The even stranger thing is the thread on the screw - have a close look!

    Puzzled Panormo?

    I don't see anything pointing to any Panormo, but I am no expert. The violin is certainly interesting though as the few things we have established so far don't really go together all that well. You should try and take better pictures of the linings at the blocks or tell us if you can see it clearly. While I think they may be let in, it is but a vision in the fog, and not supernatural eyesight on my behalf. The most interesting bit will be the neck attachment, as it is most likely original. There is no cut-out in the top plate. The shape of the heel and the thickness of the neck towards the heel are also rather "different". I wouldn't die of shock if it had a screw under the fingerboard, but that is certainly against the odds.

    Puzzled Panormo?

    The linings appear to be let in, with some uncertainty as to the quality of the photos. This is obviously consistent with the one piece lower rib and notch and points strongly to an inside mould construction. The one rib joint you show (lower bass) seems to be mitred the wrong way though. how do the others look? blank face makes a good point about the neck attachment as it looks like you either have a through neck or might be looking at a nail or screw through the upper block. Failing either there could still be a screw driven in diagonally down from the fingerboard glueing surface (which you can only see when the fingerboard is removed.
  23. I was also wondering about the role of e-string fine tuner types in this regard, i.e. English vs extending out in front of the tailpiece.
  24. This one seems to give the shorter afterlength to the lower strings. Mmmm
