I have (probably about 98% of) what has to be an old (1930s?) Modern-Bond electro-mechanical chronograph. It consists of a vertical brass tube, about 24" tall, mounted to a precision adjustable tripod base, and with a very fancy and heavy-duty vernier slide assembly on the tube, which somehow works in conjunction with a pair of heavy plumb bobs, one of which is mechanically released, whilst the other is apparently held by a magnet. The whole thing is really industrial ART, beautifully crafted, and it must weigh 50# or more, maybe 75#. I'm thinking about parting with it - but certainly not as scrap. Any ideas as to whether anyone would be interested in such a thing, or any sort of idea of value?
Yes, of course I can provide photos, but got the wild hair to do something NOW. Have tried Bing/Google/eBay, etc. - no luck so far.
Thanks in advance.
