Vintage unknown parts
 

Couple of oldies that I am having difficult making an ID on, any thoughts ? Both parts are metal.https://cimg0.ibsrv.net/gimg/www.rcu...b5ac93469a.jpg

The silver part is a motor mount/axel carrier for an old pan car. Not sure what the proper name is but it mounts the motor in relation to the rear axel. The gear looks like a main gear for a ball differential. No idea what car they're for, though.

Thank you for your suggestions, was hoping to figure out which car(s) of manufacturer they go to
