Recently got hold of a vintage 5-piece with hardware. It's 20, 16, 13, 12, with 14 wood snare. What I noticed is the floor tom is actually a different drum, with the two-piece arrow-style royal lugs, the rest being the one-piece lugs. The snare is one of those with a dual control tightner on the wires, with a big rod running through the drum.
It's old, as the bass drum has a built on cymbal mount. I'm told it had a mother of pearl wrap at one time, but it's since been removed an it exists in its bare wood, though varnished state now. Sadly a couple of badges missing and some cosmetic damage, but it's a great looking little kit.
The only Serial I can find is on the 16" - 27510 . Annoyingly, that's the odd one out!
Any help with age and model very much appreciated. Pics attached.
