It looks like I need your S745-20, weighted for 13-17 lbs. But before I pull the trigger and buy them, can you confirm that, as far as you can tell, the S745-20 will probably work?
There are no identifying stamps or other numbers on my balances. Mine measure exactly 20 1/4" in length. But they have a little "lip" on the top of the U channel--instead of ending sharply, it's folded out for maybe 1/32". Also, I can't be sure where the screw holes are to attach the balance to the frame in your part. Mine are about 1 1/16" from one end, and 1/4" from the other.
I attach couple pictures.
Thanks very much,
Rob
