So here it is - my latest barn find, a Dürkopp class 17 patcher. I just picked it up this Sunday morning from the grandson of the former owner which died in 1989 but he went out of business way earlier. So this machine probably has not been touched for 50 years or more. This is my first Dürkopp class 17 ever, I had a class 18 before but yet no class 17.
I have to figure what subclass it is. I assume it is a short arm with medium hook but have to free the hook first and check my records. Al
