A home owner from Springtown Texas says:
bottom rollers Look similar to the 84-100 you have. Top roller I'm not sure what was there. May have been the same originally.

Thanks for reaching out to us. I'm afraid I'm not sure what you're asking. Are you looking to identify your roller? If so, we would need to see a photo of both the top and bottom roller in question. We won't be able to help if this top roller is missing, unfortunately.
