Good afternoon, I am trying to identify this casement setup. It has a 10" slide track and 5". Crank handle cover. The stamp reads 30744A.
Thank you,

Hello!

Check out the 39-220B operator and 36-048 hinge set. These may be the parts you need but look over the specifications and see if they match what you're searching for. 

If you need a new cover and handle as well, see the 39-452
