Found this one at a local shop. Instantly knew it was brass from the weight.
Is the black and brass badge mid to late 60's?
Big tone knob points toward the 70's and it has the wide clamp down on the zoomatic and leedy style butt.
Somebody decided felt squares inside the shell was the best way to dampen it. I tried some goo gone but the galvanized finish is going with it. Were these shells painted inside? Looks like chrome underneath.
