A spur insert from an early Walberg & Auge hoop clamp bass drum anchor. W&A invented this now-common design and this is a very early version, with a wider footprint than later ones. See photos for measurement. It is *not compatible* with most of these anchors, and is a rare part. Nickel finish.

Good shape for its age with finish wear as shown. Joints are all good, no warping. Has not been cleaned.

I do not have the rest of the full anchor assembly.
