Hello
The adjustment screw head is damaged and the screw seems to be rusted shut anyway and won't move. So I figured it'll be easier to change the roller.
I could not find this model anywhere. I am hoping the pictures can help you help me identify what I need to replace it with.
The model I have looks like a cross between your 81-036 and your 81-071, but it's neither I can tell.
Thank you in advance
Claude
