Sure not as valuable as a mint heads-block but not less rare… yet, quite useful, as well!
I only recently found that isn’t necessary to insert a finger in C37’s receptacle (see pictures above) to reset the tape-counter, but existed this humble, cleverly made small handle protruding to make reset easier!
The new ones are individually lathed out of premium stainless-steel, while original - 60+ years old - is barely showing some rust on thread as made of lesser material.
To my experience, I only found a single sampler of this part out of 15+ C37s’ I handled: I guess these get lost quite often, soon becoming unobtainable everywhere 😳
A little, sought-after gizmo, indeed.
Anyone?
