... These look identical to Slingerland. Maybe I could add a Sling floor tom down the road as I doubt I'll ever find one of these...Bill
Lots of Japanese drum companies made drums with Slinger looking lugs like that. I had a set of Stewarts that did, and they even had reversed Slinger stick saver hoops. You can buy new lugs like that too.
So it wouldn't probably be that hard to find something like that for pretty, actually dirt cheap.
As far as the grain going one way or another, the only drums I ever saw that on the inside of shell the grain ran at right angles to the heads were (and this was very common) very cheap drums, a set of Star's I bought for $40 comes to mind. The shells on those drums would be easy to snap in half if the rims were off, they were really soft wood, and thumpy sounding.
Sometimes though, cheap drums are fun and I'd rather have a well-prepared cheap drumset than a new out of the box expensive set that no one had tweaked.
