I've had a good inexpensive experience with Aquarian Modern Vintage. I find them to be very close to skin heads in looks, feel and sound. But wouldn't your drum be from an era when mostly synthetics were used?Stephen
The drum dates to 1955-56. Plastic drumheads didn't really come out until '57. And even then they were so new, that there was some reluctance to use them at first. Calfskin would have been fitted at the factory on this one.
As far as snare side.....stern tanning offers "slunk skin" heads for the snare side as well. If you're going for a genuine calfskin batter head, I'd invest in the calf aka "slunk" snare side as well. Plastic reso heads just sound funny when used with a natural skin batter head.
