Balance Repairs in Progress

A quick learner from Carolinas says:
Looking to replace left and right balances to ensure equal support on both sides: 3340-BSI-MJ engraved in rod. For a 34-inch long balance that measures 5/8-inches deep.

Exposed part of top plastic bracket measures 5/8-inches high.

Bottom bracket's boot measures 1-5/16 in widest direction and 1-1/16 deep. Note how bottom has an L-shaped lip that seats into the window's approximate channel.

Paul from SWISCO responded:
This looks like a standard balance but with a special 15-174 shoe attached at the bottom. The top seems to match the more common 19-005. Look these pieces over and let me know if you agree. If so, I can custom make a 34" long channel balance with the 19-005 and 15-174 attached. I would also go with the 3340 option, of course. If this sounds good to you, just let me know how many you need and I will email you a custom balance order form and price quote.
