Who knew body caps could be so interesting? I noticed I had four different types of body caps. They are:

1. From a later, Kyocera made, body.

2. From an early, Yashica made, body.

3. From an Aria but not sure if it's original to the camera or not.

4. A (Chinese made?) after market cap.

Besides the differences in the patterning on the front and the text on the back, the way the bayonet is moulded is different on no. 4 to the other three. No. 4 has an extra bit that prevents the cap from fitting properly - it shouldn't be there and I always cut it out when I buy them.

I know 1 and 2 are original equipment, I know 4 isn't. Not sure about 3 though.
