This ought to be an easy question but there's a bit of a technical hitch.
One of the best collections of old scanned catalogues used to be at the website of Rose Antique Tools, but when that business closed down, the future of the library was uncertain.
As I understand it, most of the files were copied to and should now be available from the Alaska Woodworker site at
http://www.alaskawoodworker.com/old-too ... d-manuals/ - however, when I looked there just now, none of the downloads seemed to be working. Maybe that's a current issue at the Alaska site.
I also looked at the site captures of the Rose collection in the Intertnet Archive eg here
https://web.archive.org/web/20131101152 ... id220.html
which is fine for lots of things, but has no entries for North Bros/Yankee.
That's especially odd, as in my collection of downloaded catalogues, I have a little Yankee catalogue of 1931, which is watermarked as having come from Rose Tools!
Perhaps we could do a swap?
