I've got a 1950s Slingerland Student Model Radio King snare that was previously discussed in the following thread on the VDF: http://www.vintagedrumforum.com/showthread.php?t=35182
I'm selling it in its current "as is" condition. You can use it as a "player's" drum or cannibalize it for its parts. I'm honestly not sure which choice would serve you best. However, I have seen the 3-point strainers going for a few dollars on e-Bay as stand alone items.
If you've got any interest or any questions or you'd like to make an offer, please feel free to drop me a PM. I'd much rather sell the drum here on the forum than through e-Bay if at all possible.
In my opinion the pics that I've posted make the drum look better cosmetically speaking than it actually is.
THANKS in advance for looking.
