Window pieces

Thanks for reaching out to us. The second photo is a balance assembly, more specifically our 15-105 housing and Series 145 spring (sold separately). Look it over and let me know if you agree.

The lock in your first photo is not made anymore. The only products we sell that may work are our 90-252 and 90-253 cover (also sold separately). I cannot guarantee that these will work but they seem to function similarly and I think they're at least worth considering.
