  1. I doubt that anything in the polymer cores of unused synthetic strings will oxidize or become brittle, even over long periods of time. Silver will tarnish, but I have not noticed any problem playing old unused silver-wound synthetic strings that were tarnished black! (They looked really cool, too.) Steel wound synthetic strings will rust and become unusable. I have not noticed anything with aluminum-wound strings, but I suppose they could surface oxidize in certain damp storage conditions.
  2. The rib joins do look pinched like BoB construction in the profile picture. I am assuming it has a two piece bottom rib. Any "notches" in the bottom rib area? The linings to the left of the top block look newer and cut differently than the linings on the right. Is that right, or is it just the photograph? The neck looks like it might have pulled away from the button at some point, and was then reset. Maybe that pin was added then?
  3. Brush some bright blood-red paint into the gash.
  4. Unmarked vintage German bows are more valuable than new bows to some people who own branding irons and an eBay account...
  5. I think the OP's bow is nice, and Pfretzschner-like, as Blank face mentioned, but not as crisp as a genuine Pfretzschner. Just because a bow doesn't have a stamp, a discernible maker, a certificate (), or cost a pretty penny doesn't mean it can't be attractive and very good player. There were clearly some very good anonymous archetiers making very good bows (and parts of bows), and because they are "trade bows" they are very affordable. @Alexander James Stew, do you use this bow? Does it play well?
  6. I don't see many violas... Did 19th c. French violas have short necks like 19th c. French violins?
  7. Interesting hack to lengthen the neck.
  8. If it is straight, the camber is good, and all it needs is a rehair, then it is probably worth getting done professionally rather than risk wrecking it. "Valuable" is relative; "student" is an ambivalent descriptor; and it could be a nice affordable bow for you or someone else.
  9. I can't even see the nipple in any of the pictures. It is probably fine. The ferrel looks like it might be open, or maybe just an ugly repair.
  10. If a large branch or branches broke suddenly, and redistributed the balance of the tree, couldn't that cause mechanical stress that would take a few years for the tree to adjust to?
  11. Certificates can be very valuable and useful to heirs and executors managing an estate. Plus for insurance purposes.
  12. Not a "law" nor a "rule." It is actually an act of professional courtesy and respect for others. For example: That's all.
  13. There are a number of images of certificates for bows written by Hans Karl Schmidt that may be found using a web search. In each example I have found, "albeit von" ("work by") is used to point to the maker of the bow. "In my opinion" or "in our opinion" is pretty much standard language nowadays, and is used in certificates even when the certificate is from a well-known expert and the attribution is rock-solid.
  14. Welcome to MN. Just so you know, there is an unwritten guideline followed by many on MN not to publicly comment on or criticize a living maker's work that has not been posted by the maker. Therefore, if this bow was made by a living maker, you may not get the critique that you seek, favorable or unfavorable.
  15. I was thinking the same thing regarding the stubby upturned nose. It does not look like Knopf-like to me. From @Brad Dorsey:
  16. Good. Note: The ends of your tailgut under the tailpiece should be trimmed back because they can cause scratches.
  17. True, but one can extrapolate... Seeing a personal professional appraisal is still the best advice. I'd also like to see a better picture of the mortice.
  18. Not exactly sure what this means, but regardless, that is not a very good test for a crack. One would expect the part of the table glued to the block to feel different than the part not glued to it without a crack.
  19. Since you are new to MN, the term "usual rubbish" is used here somewhat endearingly for common German trade violins (which yours is) across a wide spectrum of quality and value.
  20. There are currently 2 of these bows up for auction at Tarisio, which might provide comparable price references for you. Disclosure: I have no relationship with either bow.
  21. Your bow looks damaged around the mortice, which would devalue it. But, regardless, take @Wood Butcher's advice and get all your bows appraised at least for insurance purposes, and then get them insured.
  22. Are you sure it is not a deep scratch?
  23. Maybe not so much, and certainly not if the Italian maker was importing rib garlands from Germany.
  24. Apparently not easy, but BoB construction is just one (1) check on a checklist.
