Hi, First post on the forum, I don't know if its in the right area or not. Great amount of knowledge here and I have leaned a huge volume here, just getting into the leather world, was motor trimming for years and have a Seiko STH-8BL flatbed compound feed machine and works well on leather with the correct needles, but I will require a cylinder arm machine in the near future and have found an old Adler cylinder arm 48-3 but cant find anything about it how old, what size it is, etc. Hoping somebody will have some knowledge of theses machines..........Thanks......Pete adler 48-3.jpg 4.45K 7 downloads
