They could well be from that time period, but they are still around today. We used to call them "door" fuses.
Can you guess why we consider them a REAL PITA???
Regular shotgun stick won't work. Fusing stick has nothing to grab. You've gotta climb/bucket up, remove it and replace it hoping it ain't faulted, or find a large closing fork and try it very sloppy.
I HATE when these things happen!!!
