Thanks, Journeyman - Got that book. It's very good. However, I have heard (as recently as last weekend) of a many book (possibly paperback) series on chronographs. That's what I'm trying to find out about.
there is a 23-volume series by william o. smith.....you can check them out for no charge if you belong to the american watchmakers and clockmakers institute...here is a link to their site if you are not familiar with it http://www.awci.com/
I don't know the book you are talking about but one of my other favourites is The Chronograph its Mechanism and Repair by B humbert who was a teacher at the watchmaking school in Bienne. If you find the book you are looking for I would be interested to know the title and author.
The multi-volume set guychampeau is referring to is called the "Assemblegraph" (sp?) series. I used these back in 1970 while at "Tick Tock Tech" (Gem City College"). There are several calibers covered, but naturally, none after the books were written. Given those limitations, there is a WEALTH of information in the books.
The NAWCC Library also has the "Esembl-o-graf : the world's first fully illustrated text book on chronograph repairing and adjusting, Venus Cal. " by William Smith. You can search the Library catalog at http://www.nawcc.org/Library/warning.htm Click on Continueto Library-On-Line and then Search Catalog. As stated above, it is 23 volumes, so if you have a specific question, it might be easier to first send a request to firstname.lastname@example.org and I could look up which volume(s) may be of interest to you.
Thanks, Guys - From the description I got last weekend, I think it is the 23 volume set. Don - Good to know that NAWCC (and probably AWCI) has it in their library. I guess I'd like to get a feel for how long ago they were published, so I can decide which ones I might like to check out.
