A handy person says:
Hello I have a pair of balances without your 6**, 7**, 10** numbers to indentify.
What I can clarify is the following #'S B70 4#19 4-82 in heavy stamping.
next is 11600-2 near the anderson logo stamp.
and 11600-3 near the patent numbers
Window is a double hung with the following dimensions. bottom = APPROX.
19hx24w AND top is approx. 20Hx24w
Thanks for your help.

Thanks Mike
I was able to crack open the two units and restring them.
Thanks for your replies and if I need any more of those units I now know which ones to get from you guys.

I wonder where the handy person in PA got the original 2 mm braided cord (nylon?) that looks super strong?
