Hello,

It's tough to be sure with the screen and operator still installed, but take a look at the 39-188 operator. This appears to match the zig-zag shape of the gear arm, but please confirm. Review the specifications and see if they match up with your assembly. If so, we also offer the 39-187 opposite-handed version.

If you need new hinge as qwell, we offer a selection of 4-bar hinges, which you can view here. Take a look and compare the specifications shown on our product pages to confirm the best match. Thanks for posting!
