balance spring for Atrium window

A home owner from Hayward, CA says:
I want to buy the channel balance for dual non-tilt sliding Atrium window.
The length is 33 inch. I did not find analog. The closest one is series 390 but not completely. As far as understood I have top - 19005 and shoe - 15001. Could you look at my pictures and advice what model should I buy?
On the metal part there is the following marking: 86 32-3 GA5 CMC 21
