Caldwell channel balancers - need help with top & shoe identification

Question

Hi

I end to replace 2 sash balancers that have following imprinted on them

"12 5 KR CALDWELL"

The sash weighs about 16 lbs, and the channel is 13" long by 1/5" wide (9/16" actually).
Based on this info, I believe I need 380 series balances.
However, I am not 100% sure about the top and shoe...

My top is winged and (looks like 19-005 but not sure), and my shoe is not winged...

I have attached several pictures in hopes you can help me identify which balancers to order.

Regards!

Thanks for posting. Before we can offer an applicable substitute for your channel balance, I just need a bit more information regarding your bottom shoe. Please refer to the chart below and pick out your shoe from the examples given. Keep in mind that although the difference of a fraction of an inch may not seem like much, it is in fact vital to the operation of your balance, and it is important that you get as exact a measurement as you can.
