B-16 Amp Head and Cabinet c. 1964. This is the cleanest and most complete silver tolex B-16 stack that I have come across.  The serial number on the output jackplate of the amp head matches that of the input jackplate on the cabinet, which houses four original Jensen C10Q ceramic magnet speakers.  As the B-16 model tends to be under-powered, this amplifier was fitted with Hammond transformers to take advantage of its full sonic range.
