@JohnD Well, now that you mention it at 3:20 a.m. my time:
19-51-21 [My home room] and 46-12-53 [My gymnasium]. "Dudleys" of course.
If you're collecting oddities: The same local progressive die company that was stamping out faces and housings for Dudley combination locks in my area was also stamping out accessories for Cinch Jones black plastic barrier strips in all their sizes and variations.
Now for something truly bizarre: The part number 141-Y has just come to mind as the number for the 90 degree "Y" accessory that extended points on your 141 series blocks so they could be wired from beneath their mounting surface.
There's one for the seriously anal / nerdy geezers among us.
[Now where have I left my slide rule and pocket protector?]
Toodleoo!
Ron Hebbard.
