Bill Wahl down at Mesa Typewriter Exchange was kind enough to allow me to bring my scanner & a laptop down to his shop and scan in some of the old serial number info he has in his large file cabinet full of dealer catalogs, repair information and other ephemera he’s been collecting since his grandfather opened the shop in the 1940’s.
Today he brought out the National Office Machine Dealer Association Blue Book binders and I picked out the sections dealing with serial number to year of manufacture tables and the font tables sections of the 1980, 1964 and 1961 editions. In all, I scanned 54 high-rez samples, and will be distilling these down to postable jpegs over the next few weeks. Loads of fun info!
So, here’s the first batch: from the 1980 NOMDA Blue Book, “Approximate Ages, Standard Typewriters”. Click the images for hi-rez printable versions.
