Thanks Vintage,
I believe the drum is in round. really close. I carefully and evenly tried to tension the head down over the shell hopeing the head would pull down to fit. no go. It might be a hair off. Like you suggest, I just need to try some differnt heads. Also after further research I have nailed this drum down to be a 1936-39 Radio King becuse of the type script on the rims.
If the old heads squezed the shells you would think new heads would fit.
But I also noticed the batter head was pulled down more. like the skin had given more aroung the wire hoop. not the rim. so there was less space between the rim and head. There was a little more space between the rim and resonant head. of course age and if it was performed on .
From Slingerland History site.
"1936-39: The Radio King line of drums first appeared in the 1936 catalog. These drums had the distinctive “Slingerland Radio King” stamped in the metal hoops. On very early Radio King drums, the words were actually engraved into the top rims " Just like this one. The script on the rims of this drum are exactly like the the ones in the pic.
Amazing this drum is or close to 75 years old. Nickel doesn't shine up like chrome but those little clam shell lugs are built so good. springs, tension rod inserts.
I will try some different head sizes and see what happens.
Maybe I can get away with this little vintage set up. I think this drum should have one more performance. I will take this set up out one night for a jazz performance.
