That's the head from a B-115 combo amp, not related to the B-15 family at all. They were sold in the late 70s, originally as a combo then later as a head/cab. The B-410 was the 4x10 version. The number of amp model numbers listen on the back was due to the use of the same chassis for multiple amps.
Just call me B-String 2
