These parts came from a box of vintage parts, I did not pull them off a bass guitar. It was in a bag labeled Miscl bass parts. They appear to be a used bridges off 1960s to 1970s basses. They might be off of Made in Japan basses of that era? The single bridge without mutes looks similar to the type of bridge used on old Teisco, Kay, Silvertone and/or other MIJ basses. It has a lot of wear, rust and corrosion. The two bridges with mutes don't have much if any wear on them, unclear if they were even used on a bass. Some of the felt mute pieces are missing. I've never seen bass bridges like these. If anyone has any more information on these parts, please let me know and I can share in the auction notes.
Will ship the the USA only. Shipped via USPS Priority Mail for a fixed shipping cost of $8.00. Please see my other auctions for additional vintage guitar and bass parts. Can combine items for single shipping charge.
