Additional Details


The pictures below were
sent by a fellow in the USA a while ago but he never sent me any details
or specs.  He owned the recorder but knew absolutely nothing of it’s
history, age or even the model number (there was none  on it).
It’s obviously a very old machine and it also has an AM radio tuner built
into the front panel which was quite common for early American tape recorders.
Masco made some of the first commercial recorders from the late 1940’s
through to the mid fifties – I’m not sure of the model number of this
one but after a bit of detective work I think I’ve identified it.
Apart from the tuner at the front, it seems to be identical to the 1950
model 375 pictured at left (from a 1950 Sam’s photofact book).
