You are looking at a vintage Japan import bass guitar bridge part from the 1960's 1970's. 

Part of the collection of items I kept upon retiring from my business after 38 years, Guitar Emporium, in Louisville, Ky.

Very good condition. Two piece bridge. Missing one saddle screw, and will need new saddles.

Item will be securely packed and promptly shipped.

Check out the pics.

Feel free to ask any questions.

Thanks!
