If you like old photos, I have a roll from around 1954. This is long before I joined the company. My boss was one of the first in London, Canada, to open a full service TV and radio store. They must have been fairly successful to support 5 service vehicles.
The right side was an old add-on to the building and he operated out of both units (the family owned the building).
Both table top and floor standing models.
The right side had more display space but had a separate entrance. Looks like a tube tester on the left wall. That little room in the back is where I stared my career but they were no longer a TV store then and moved into finance.
Full service bay in the back.
They also carried a lot of radios. This was in the front window.

One of the floor models. This was high-def in the '60s.
