Can anyone tell me what this part is too? it says: CPA TP-RT 252 (its an old mirror) Please see pics

Looks like a motorcycle mirror, to me. Do you have a shot of the attaching area?

Keiser31, Attached is a picture of the attaching area. My friend who gave this to me had a couple older European motorcycles, Triumphs, Indians Etc.

Yep....definitely a motorcycle or moped mirror.

Great, thanks so much for pointing me in the right direction!

Looks like a Eruo item, Japanese were not as stylish.

`no answer but maybe some help:

The brand name is "CIPA", today they're out of Michigan, and still do mirrors.

A vintage nos mirror with the cipa/diamond logo like yours sold on ebay #221322862204.

description says "made in France" and listed several 50's or 60's French autos.
