Please look at this roller assembly and tell me what you have that would match . I'M Going To Need A Large Quantity 100 or so.

Do you have a part that would match this one? We Don't Want To Make any Mistakes Thank You

I'm afraid that I'm unable to locate the exact roller you have. It must be very old. I pulled up that patent number and didn't get any reliable results, but start by looking at our 81-148 and 81-258. Could either one work as a substitute?
A professional from California says:
81-258 often has the same patent number. Probably a good substitute. I have not seen this exact roller, so I can't be sure.
