I have a 1948 which was found in my attic! Named her Shirley after my DML who originally owned her.
She hadn't been used for 20+ years. Cleaned her up, oiled, DH did something on the bottom (oil or grease or whatever), plugged her in and she purred. I swear she was smiling on the first run, so happy to be in the light and feelin' the love.
