Mikunis - name, value, repair?

Hi! In my box of parts to go with my bike I received a set of extra carburetors - I’m sticking with Keihins, so I’m considering selling these.




First, I’d like to know what model they are - I can’t find them named on the bodies. I think they’re from a GPz? Secondly, one of the top covers is damaged:




It goes all the way through, but the diaphragm below is unharmed. Is this something I could fix (most of the plastic is still there, just pushed aside) or would it be prudent to source a replacement cover?

Thirdly, I’d like to know a fair price to ask - I assume it would be higher with a non-damaged cover. I’m comfortable disassembling them to show condition if that would make them more enticing.

Thank you for reading, and I look forward to learning about these!

I am not able to view any of the images you loaded.

Fixed! Thanks for letting me know.
