As a 'Newbie' I'm browsing the net to discover technics , guidelines etc. on my new hobbie.
I found that document from US war department dating 1945 about : 'Ordnance maintenance for Wrist watches' ...as you'll notice it's also an introduction manual for vintage watches, and some american watch models
Looking at it, I thought to myself how lucky we're to have internet and online courses ...
P.S : name of the attachment, is the official document name in US army archives
Inspiring stuff Andy! Hope to pick up some more to have a go at, I'm on the look out on ebay constantly, but don't see very much going sub £5, most stuff has a starting price higher than that . Hopefully post lockdown I'll be able to get out to some flea markets and fairs again.
