I'm new to this forum, so this will be my first post. I've been playing for many years but have never really been into vintage stuff until we cleaned out the house after a distant relative who passed away recently. Her late husband was a devoted drummer for most of his life, and some of his stuff has now ended up in my garage for the time being. One of the items is this single head tom, approx 12" by 6,5" (it's actually metric 300mm by 165 mm). Three-ply shell, rounded reinforcement rings, internal damper and the most odd thing: three tom-leg mounts. As you can see on the pics, it has slotted tension screws with small claws. The rim is missing, but with it came a real classy brass flesh-hoop.

I haven't found any markings, but I would hazard a guess that this is a 1950s drum.

Any suggestion as to what kind of drum this is and how it was used would be appreciated!
