Replacement Channel Balance Spring Mechanism

Question

I am needing to know what I have in the pictures so I can purchase new ones. Please see added photos and let me know my options/part #s etc.

Note there are two different parts for two different windows but they are made the same way. There is only one pic of the one with code 2730 and it is a BSI (Window Bedroom).

All of the other pics are of the 2740 (Window Breadfast).

Thank you for your help

Thanks for reaching out to us. based on these photos, my top recommendation would be the S395-28. This has a 19-005 top and 15-001 bottom nylon fitting, so as long as those match up then you should be good to go. Look it over and see what you think.
