Generally only the Radio King models had the snare bridges (or whatever you call them) but in later years Slingerland wasn't necessarily "married" to using the solid maple shell exclusively for these models despite what the catalog said. There were "student" versions in the catalogs with three ply shells but they lacked the bridges. Very easy to imagine a special order version of one of those student models with the bridges added and/or a regular RK being built with a standard 3 ply shell.My guess is those hoops are modern stick saver imports. I bought some for a vintage Slingy snare (metal shell) and the splay was bad enough that I couldn't use them.
I agree with K.O. Hoops are not original, hence the splay. Badge and hardware layout date drum to '59 or '60. Slingerland was no longer using the "Radio King" name for it's top line drums during this era. As K.O. said It could be called a Gene Krupa model with a 3-ply shell or a Student Radio King with bridges and tone control. Most likely value is not that of typical Radio Kings.
