Hello,
Unforutnately, we do not carry an exact replacement for your handle, which honestly looks more like some of our window locks. It's possible that this is an older style or someone may have installed aftermarket parts at some point. In these cases, our best recommendation would be to see if you could install something like our 82-005 surface-mounted handle set. Keep in mind that it would require making new holes and other modifications may be necessary. We can't make any guarantees but review the installation video below and see what you think. Thanks for posting!
