Thanks for posting. This looks like either an S351-27 or S390-27. The only difference between these two channel balances is the bottom shoe depth. See the image below. Measure your old balance's shoe to see what matches best. For a stamp option choose 2620. Let me know if you have questions.

Comparison of the S351 and S390 balance shoes.

Thank you for the comments and answers. It's 1 1/8.
I have another question there's a piece of plastic that goes at the top of the movable window frame
It screws in with one Phillips head screw
Do you know what it's called?
Do you all sell it?
It's one and 3/8 tall. By 5/8 inch wide.
The top is 7/8 by approximately 3/4
