replacement Kinco channel balance

A home owner from Orlando, FL says:
Have 13 year old Kinco windows. I think model M50.

Need 2 new 1/2 channel balances 21" lenght. Looking through your products appears to be a 19-005 top & 15-002 shoe.

Can not find any marks stamped in metal, but it looks like 20 5(or 3) BR CALDWELL is printed in ink. Attaching pictures. Can you figure out what I need to order?

Thanks for your help, Pat

Thanks for posting. With a winged top attachment and non-winged bottom attachment, your balance will have to be custom made. Before we begin, however, please confirm the stamp on your balance. Is it 20 5, or 20 3? If you aren't sure, please take a picture of the stamp and upload it here for me to see. Thank you.
