For over 50 years, my dad, who is about to turn 80, has used the same old buzzard Remington portable typewriter. He'd occasionally have to haul it off to a repair shop for a tuneup and overhaul and then he'd be back pounding the keys, writing letters, lecture notes, and articles.
Today my mom called and asked if I knew of any typewriter repair shops in my area. Seems the old Remington crapped out and there's no one in their town anymore who fixes typewriters. Since I own a couple of old mills myself, I know we don't have anyone around here anymore either.
Google turned up the website below. The site includes a list of typewriter repair shops in the US and other countries. Hopefully, out of the listings we'll find a reapirman who can get my dad's typewriter clacking away again. For those who own and enjoy the old "mills", here's the website. Enjoy.
