This is a tom holder receiver, likely from a Yamaha 12-inch tom dating from the late 1960s to early 1970s. It has a curved structure to match the shape of the drum. There is a lot of rust and pitting, but there is no play in the holder receiver, and it functions perfectly. The distance between the four mounting holes is approximately 65mm. If you were looking for one, how about it? *This listing will be up for a while, but will be discarded if there is no interest. *Shipping may be changed to Yu-Yu Mercari delivery.
