Hello all, i am new to your community. I have dabbled for a few years with leather work. I recently received an Adler 30-7 treadle hand crank machine. The price was right. Free. I am in the process of disassembling it and getting it running. The problem I have is the teeth are sheared off the gear on the hand crank. Can anyone help me find a replacement gear. Thank you so much. -matt
