Vintage 50s WFL Ludwig Block Accessory Cowbell Holder Mount Clamp On

Wonderful patina. Vintage 50s WFL Ludwig Percussion Mount. Includes only what’s in the pictures. Missing the part that screws in to mount a block or other part. Typically clamps on bass drum. I believe it’s from the 1950’s. Used. Shows some wear and a touch of rust. Please refer to the pictures which are considered a part of the description.
