So what was it used for in 1922? And what can i use it for now?

Source of tin to provide 1% to 3% tin for better fillout when casting lead. Sb or antimony helps make a harder lead, Cu or copper helps make a tougher lead.

This says it is 3.7% Cu, 7.5% Sb, balance tin.

However a different source says it may be 30% zinc and zinc will mess up lead for casting. You can test for zinc with acid.

Doing your own Google search is a good thing, I scrounge for lead and so I found the identification of this ingot of interest in case I found some someplace but you really might want to at least do a search and share what you found.

this one says Bearing tin alloy;CU 3.7;SB7.5;bal SN cast 1055ts;9400YS;3.5EL;3.9RA
I will have to do a lot more searching
