Hello All. I found this item at a 1920's home site. It looks strangely familar but I can't place it...maybe automotive related? Any ideas? Thanks.

Hello creskol. Dang that is one good ID on very obscure piece of hardware! I looked up 4-note pitch pipes and see objects of the right size and shape, so I'm 'gonna mark this one as solved. Thanks for the reply and the great ID. C9
