  1. The MOP looks like European oyster, which means it is after the end of the freshwater mussel (practically extinct in Europe except for a very few rivers in Norway) and the start of international MOP trade. So something after 1850 and before 1880.
  2. Maybe you should try gut strings on your modern cello too? Having changed from what-was-on-it to Kurschner gut strings on. bass gamba, I understand very well what you mean by articulation and consonants. Cellos were played with gut strings well into «modern» times, so there is nothinh inherently wrong with using gut strings with modern setup.

    Pochette violin

    http://www.thestradsound.com/maestronet/stradivari-forma-by-addie It’s in there. Useful link to have.

    Pochette violin

    There’s a pochette plan in the Addie collection here. Looks interesting.
  5. I have one like that. I call it the Frankenfiddle, since every part is a different wood. It sounds like it looks: Haphazard patchwork. I am sure it was made by a luthier’s four year old som playing on the floor in daddy’s workshop,
  6. In the UK you have Tarisio, Amati, Bromptons, and maybe even Ingles&Hayday frequently have instruments in your price range. You are just a few days too late for Tarisio, Bromptons and Amati's October auctions, but there is a "Single Owner" auction currently at Amati. All violins are marked "A Violin", but I think there could well be some nice ones in that lot.
  7. Because the wood in the top is chosen for acoustical properties, not for beauty or longevity. There are many woods which look nicer and keep polish better, and are also less prone to cracking. But they don’t sound good...
  8. That has been done: https://en.m.wikipedia.org/wiki/Vebjørn_Sand_Da_Vinci_Project It should really have been a catenary arc, which is much easier to construct than to calculate: All you need to do is trace the curve if a chain, suspended from both ends. Mr Sand decided to depart from the original drawing so much that I wonder hiw they could call it the da Vinci Project. From what I have seen violin arcs are rarely catenary and maybe even more rarely circular
  9. I confess that I am baffeled, nay flabbergasted, by this recent «Leonardo’s bridge» hype. Look closely at the original sketch. Then at the CG design. Are they the same? Does every curve match, or are they even remotely similar? Did Leonardo specify the shapes of the stones, or are they a modern approximation? Did he really propose to build a bridge across the strait of Bosporous using stone blocks weighing in excess of 1000 tonnes?
  10. Thorval H(or K) Fouxemberg is what it looks like to me. I can't make the first letter of the surname be anything but an F, the next letter is o or a but most likely an o; the third is an overlined u. The following x being slighty larger than the rest is not that uncommon. E and m (or n) are hard to make out but I think it's -em-. And then probably ending in -berg. The -d at the end of Thorvald is silent in most dialects, so it was not uncommon to drop it. Very many names had a lot of "alternative spellings" in the 19th century and before: Torval, Torvald, Thorval, Thorvald, Thorwal, Thorwald, and even Thorwaldh are known spellings. Not likely to be Swedish, very unlikely to be Norwegian, possibly Danish, most likely German.
  11. Maybe Guillaume in Brussels? Or Schmidt in Dresden - those two were the first I thought of.
  12. Oils and resins are really fatty acids, so adding lime leads to saponification. Saponified oils and resons have drastically different properties than the raw fatty acids, although not as much as simpler fats like e.g. palm oil (look at your soap, it will most likey contain sodium palmitate, which is the reaction product of lye and palm oil). Calcium soaps tend to be hard and practically insoluble, which is just what we need for varnish. Addendum: Aqueous solution is not needed to call an organic acid an acid, it is enough that the formula contains one or more COOH groups.
  13. In from the sidelines of not knowing anything at all - what about the old integral bass bars? They were used for a very long time, and must surely have worked well enough? Was there a standard thickness for those too?
  14. What about compressional anisotropy? Is the Lucchi meter always used to measure speed of sound along the grain, or are users sloppy in the directionality? Speed of sound is one important measure in my work (oil geologist, specialising in wellbore log interpretation), and velocity anisotropy is one of the things we always have to watch out for. We tend to state velocities in microseconds per foot, one of the very few non-metric measures we can’t seem to get rid of.
