Del Mar Double Roller with 1.125" Dia Rollers

A handy person from Dayton, Ohio says:
I have double roller assemblies marked Del Mar Patent 3,670,357 with 1.125" dia rollers. I found your previous discussion from customer with same brand and patent number but identified 1.5" dia rollers.

The closest match I found by images and descriptions was for an Acorn 81-030 with 1.25" rollers. I think this should fit, but thought I should consult before ordering.

Please find attached two photos with dimensions and view. Thank you.

I agree, the 81-030 looks like a close match. I would just triple check your dimensions to make sure they match ours.
