Your operator is similar to an old Look/Rusco operator that is no longer made. We still have the right hand version under our 39-350, but the other side just isn't around anymore. Also take a look at the operators used on Pan Am/Daryl windows like our 39-016 and 39-017. You might be able to adapt these to your window as a replacement. |
