Quick question! I got a 201 at an antique shop after Christmas and it is in great shape although missing a few key parts. It is missing the bobbin cover and the tension assembly. Would a tension assembly off a 301 work on the 201? I have a 301 that a supposed "professional" shipped me a couple of years ago in a toilet paper box with cushion foam thrown in. The 301 arrived with the main shaft bent. (Yes I got refunded after I sent him the bobbin case and I kept the rest.) I would check myself but the 301 is in the shed loft and I don't want to disturb the chickens that are there.lol. Thanks!
