single hung non tilt channel balance is 21 3 FN CALDWELL

Question

i have an existing single hung non tilt window with a channel balance with one marking of 21 3 FN CALDWELL.
i have no idea of the window manufacturer.
The length is 22" NOT including the top plastic piece.

i believe that i need to replace with a 22" 385 series 2110 option. Please confirm.

Thanks
