Hi, up for auction is a Slingerland Radio King L-Arm. This model is made of 3/8" aluminum, and is designed to fit the Slingerland's 1940s-50's clamping hardware. It has a fixed height of 22". From the bend in the L.( WHICH MAKES IT PERFECT FOR A SPLASH CYMBAL) This arm was removed from a 1954 Slingerland bass drum. I was in a dispute about these arms these being aluminum, but after careful research, Slingerland did produce them, along with chrome and nickel options. I will also supply a new rubber cymbal sleeve, thats not in the photo's. T is a fixed shipping of $9.95 anyw in the lower 48 states. Thank you.
