Casement crank openers

Hi, the casement window crank operator doesn't work and the hinge is broken. I can't find the manufacturer's name on the window. Also I can't replace the window because it was installed outside first and then put inside stucco later.

I only found the information on the hinge is:
INTERLOCK
WORLD PATS
P1090 a1

The window I measured from inside of the house is approximately 21.5" width x 34.5" height

Could you please help me find the parts to fix it?

Thanks

Pauline

See our 39-091 and 39-092 Roto Short Arm Operators. Unfortunately Roto has discontinued much of the hardware needed for these operators to work, including the bracket arms that link them to the sash. You will have to reuse your old ones if possible. For a handle that works with these operators see the 39-224. For new hinges, see if you could replace them with our 36-048 Hinge Set.
