Hello, The operator shown in your photos looks like an old-style Roto assembly. You are correct that, unfortunately, Roto stopped making these and the only product currently available is the base itself; our 39-091 and 39-092, which are modern styles of your older part. We also offer the 39-224 folding and 39-230 standard handles for these assemblies but, unfortunately, the link arm that connects to the sash is obsolete and there is no known alternative. We apologize for the inconvenience. |
