The top one looks to be the Danielson design, probably after being bought out by the Plombpire. Maybe 1957?
It is marked "R97" near the hang hole on the side showing.
On the
other side, it is
stamped FORGED ALLOY STEEL P
On the
other side it has
15 and
MFD. U.S.A. forged in
So... the likely suspect is the old J.P. Danielson plant again! (I just ran into one of these a week or so back)
Square gullet.
Nice unit. Way nicer than the one in the middle. (I think Indestro outsourced that one as well.)(For that matter, I think they outsourced all their adjustables.)
I might offload that Diamond - it's whacky. The screw holding the adjustment wheel appears to be "stuck" - turning the adjustment wheel turns the screw. Turning the screw turns the adjustment wheel. How do you fix that one?
