I popped the heads off of the bass drum. (see photos below) I found a few interesting things.
1. The bass drum has the same 6-ply maple shell as the snare drum, only the bass drum has re-rings - the snare did not!
2. The interior is painted in the same black paint and it has a gold W&A stamp inside just like the snare, only the bass drum does not have a stamped serial number - the snare drum did. I'm beginning to think that the snare drum may have been added to the kit at some point with the other drums in the kit being of older manufacture. Food for thought.
3. There is a tacked-on red felt muffler inside the drum that I'm not quite sure is factory installed. Does anybody know if W&A did stuff like this on early kits???
There is one small bubble in the wrap on the bottom of the drum that I will glue down. Other than that, the wrap is tight and it will clean up really nice.
The bearing edges are as new as the day they were cut. Inside, the drum is immaculate and in pristine condition. Lots of work to do on the hardware, but it shouldn't take long to have this one 'refurbed' and back up and running in short order.
Here are some shots of the drums' interior: see below
Going to work on it now... more later.
