Hello!

I purchased a 50s Slingerland radioking snaredrum. (Dog tag badge, streamline lugs, clam-shell strainer). I'd like to ask about the size. It has 6 inch deep shell. I didn't find 6x14 snares on the catalogs at all. Is it a rare size or it's not original slingerland? It looks like original...Thank you so much, Hunor from Budapest!
