Hey there!
Thank you for reaching out to us. We're happy to help with this. However, the top fittings for your balances are too damaged/missing. Is there an identical window in the house? If so, we can use that window's hardware as a reference.
Hmm, I'm still not entirely sure if the top fitting is originally wingless or if the wings have broken off. If the top fitting is indeed originally wingless, I'd recommend the S351-30 or S390-30 with the 2930 stamp option. The best match will depend on the depth of the bottom shoe as shown below. Take a look at the specifications and let us know if you have any questions!
