Up for sale today is nice front brake caliper for an early Honda cb750. It  work on the 1969-1972.  All the threaded holes are nice. There are no cracks or broken pieces. As you can see, the piston is not seize up inside the cylinder, like most of them. It is nice and clean. I am throwing in the piston, screws, and that piston cap - everything you see in the pics. I added a pic of the microfiche for your reference. The piston itself does have some pitting, but they are available aftermarket if you feel the need to replace it.
