777 Solder?

[EMC45]

I got 5 sticks (1lb) from MGD45 the other day for my birthday (what a guy right?) It is 777 solder and it says National Lead Co. on it as well. What is the content on this solder? Any help will be greatly appreciated..Evan

Are you sure its 777 and not 111.
National Lead Co. 111 Broadway. NYC NY.
They put the 111 on their bars made there.
Its likely 50/50 but could be anything.

I agree, most probably 111 and it is 50/50.

Most definitely 777. Just had it in my hand. 50/50? Cool.
