When I was restoring pumps I used to buy these locks at Atlasta Lock in Portland. They still had them new. That was years ago but worth a shot. Have you checked any other lock shops?
Great recommendation Petrpumps! I have not tried that yet. I will contact a local lock dealer and if that doesn’t work I’ll try Atlaska. I used to live in Portland.
SloDave - I’ll let you know where I find them and share the info once located.
