Which I believe there is some of those in the panel pictured here also.
What kind of breaker is this?

I noticed the new dummy breakers also have a blank front. I was thinking that as a first generation thing they might have used parts that were already in production.

Can you get a picture of the internal wiring? How about some better quality pictures of the breaker with no handle?
Is there a notch in the place where the handle should be or is the handle broke off or what?
It is hard to tell from the previous pics.

Where do they mark the size on the slotted type? The rotating key style has the size stamped near the keyhole.

You are correct.

There are both dummy breakers (below the key-operated breaker) and normal blank fillers (just above the key-operated breaker).
Dummy breakers do not contain the words On and Off.

Isn't the one below just a partial view of a 3-pole breaker? See the wider shot in post #16.

These pictures are from a panel that went obsolete back in the the mid 60's. 50 years ago there was no code requirement that the rating of the breaker be visible when the breaker was installed.

Maybe, can't really tell. But, it is still what a dummy breaker looks like.

I don't quite go back that far.
But I do remember having breakers that required you to look on the side to determine the size. Whether it was rubbed off numbers or just some old breakers with no numbers on the front I do not recall.
