I believe I have Kinco windows which are no longer being made. I see that you can supply replacement parts. I cannot find any numbers on the balances or the boots but am including photos to see if you might have something that will work. I had ordered balances from a local company but they could not find boots that would work with it. They ordered a 22B tilt sash measurement of 23" with a hook at the end. Any help you could lend would be greatly appreciated Thanks!!! Katie
Balances Length: 23" width: 10/16" rear: 1/2"
Boots 1 5/16" x 1 4/16" Width: 9/16"
