Kiev Body Cap......H E L P !!!

I feel foolish in asking this, however I'm stumped.
I purchased a "Kiev" Body Cap off eBay a few days back . It arrived in the mail yesterday.
For the life of me I can't get it to attach to any of my Kiev's or Contax camera bodies. This leads me to think it is the wrong cap.

If you will please look at the eBay auction, #250263294350, and tell me if it looks familiar to you, I would appreciate it very much.

These caps are darn hard to find and if I'm doing something wrong in trying to attach it I would like to know.

PRETTY STUPID, HUH ??

Thanks,
Steve

Hi Steve,

have you tried asking the seller? It looks like it goes over the whole mount just like the J-9 or J-12 lens and then you just twist it just like the lens... is it too tight or too big? I'll give it a spin just in case also when I see you after the holidays. [:)]

Too small. The bayonet on the body protrudes too much for the cap to cover.

I emailed the Seller prior to asking here, so I'll have to give him some time to reply.

Thanks, Vlad.
