[Milsurplus] RBB and RBC serial numbers

[Robert Flory]

Hi lovers of black and wrinkly radios,

Would folks check their RBB and RBC receivers and see if anyone can find an exception to my observation that RBB receivers carry odd serial numbers and RBC receivers carry even.

Seems to hold true with most of the ones I hang around with, which are all -0 or -1 types.  -0 being my notation for no number following the RBB.
