Anyone have any ideas on this one? Marked L A and a triangle with nothing in it. Part number 145-0115. sizes 7/16, 1/2, 11/16, 1, 1 1/8.
I would start guessing L??? Acetylene, as it looks somewhat like a torch wrench in shape...
(Or Liquid Air Co, but i dunno if LA is their logo usage..)
Probably Liquid Air.
Those things make real good deadweights on handlines.
On a bad day they also work as emergency plumbbobs.
