Half inch spacing comb binders.
Hi folks
Trying to find comb binders where the distance between the combs is half an inch. Everything I've been able to find is 16mm (5/8 inch nominal) and is too much spacing.
This is to rebind the calibration booklet for a BC221 frequency meter. The original 1940's binding is breaking up.
Any sources you know about?
