Window Stkr: H-R25-48x80, Series 40-17 Single Hung. No markings found on orgnl part. Holds 3x #4.0 35" P coil sprngs. I added captions to pics of 20 yr old, UV baked part based on beam caliper & quadril paper 4sq/inch. Seems similar to ur 15-205. Asking for verification or other suggestion.

Hello there. Are the springs 3/8" thick? If so, then they're the Series 165 3/8" thick springs, and the 15-205 Triple Support is indeed the correct choice.
