Looked at a service up grade today. First time I seen a 120 service in a while. Pretty clean and I. Good shape. Can any of you old timers guess an age? I'm assuming original to house and original fuse maybe 40s?50s?

Not sure of the service but that particular meter is 1940-1954.
The JA and JS series used the “new” alnico magnets.
guess what they were made of…

That's for a residence?!

No 240 loads obviously.

Is it just for a common space or something? Lights and receptacles?

I was surprised to see you say it was a house, but I guess if all the heating and cooking is combustion of some sort then 120v service is possible.

How common was that?

In the olden days, existing houses were electrified with a single 30a 120v service, often with both conductors fused.

The fused switch in the pics has the line incorrectly fed to the bottom*, in addition to the paralleled small conductors.

* Unless that single fuse is the entire service for both meters, which it appears to be as I look more closely.
 
I have seen similar with a screw for n fuse. My first as an apprentice. I was like wow that's cool. All gas and a few lights and couple of recpticals all knob and tube. As a journeyman I have built 120v service for traffic lights and some pole signs. Now pole signs need a 400 amp service.
My have things changed over the years.
 
In 1978 when I first moved to NC I remember seeing a 30 amp 120v service. The overhead came into the attic into an open single fuse block. I can't even remember where the meter and panel were. I had seen a few back then but I haven't seen one since then

It was very common around here.
In the early 80's as an apprentice and then first year JM I must have upgraded between 18-24.
One town managed it's own power. All the underground services were 120/240 almost all the overheads we're 120.
If the customer didn't want to pay for the underground they kept them at 120.
We did quite a few 120v 200amp services in that town.
It was one of the more upscale towns 12 miles or so west of Boston.
