Nope. sorry @emmamia. Still don't know what it is. I can't see a comment by countrygirl. 😕

Because those parts are for automotive industry I can't show you the full photo of the pieces. Basicly it is a half of cm thick metal sheet cut in the designed form. It has a few holes with,and few holes withouth tread. They were placed in a specially designed box, which enables the pieces safe transportation to the customer. More info would bring me in trouble.😉

Ha, ha, ha! Thank you for the extra information @emmamia. It sounds like you made a very interesting find! 😁

She can't see me bc she muted me. ??

I think she thought you knew exactly what that piece is. And nothing else...☺
