I'm going in deep (as long is possible) in Ets Clavé Paris history and I see there is very few original material on the web. The most important source is the 1985 catalog and price list published on a french site, but we need more!
Some information is on advertisement like the one in the Nautical Almanac Year 1979.
There is on Clavé also a Facebook page.
A good source in USA was probably the Cross Optics Catalog (I'm aware of the 1978 version at least), that was sold on some site a couple of time. So, does someone have one copy of this catalog and should be so keen to provide me a scan of it?
Obiouvsly any other kind of Clavé information should be precious for me. So, please share! And so do I.
Thank you very much!
