I acquired these in a trade, and don't know which Bronica model they
fit. The body cap fits into an opening that's 66mm (or 2.6 inches) in
diameter. The rear lenscap is a little over 56mm (or 2.2 inches) in
diameter, and has three tabs which extend out slightly. It is about
46mm (or 1.8 inches) deep.

Both are in good, usable condition but with lots of scuffs and
scratches. On the other hand, if you need to protect a rear lens
element, or to keep dust out of you camera body, these will work as
good as new, and cost much less.
