Semco operator replacement

Question

I need a new operator for the window shown.  It is a Semco and has the EntryGuard and 30744 stamped on it.  It is the right side (when looking from the inside) of a three panel window.  I noticed that the straight are appears to connect with a screw rather than sliding in like I noticed on many of your similar parts.  Any help with identifying the proper replacement part would be greatly appreciated.

Check out our 39-031 & 39-032, or our 39-155 & 39-156. The only difference between these two sets of operators is slight variations in the length of the link arms, so compare with your old operator to see if either matches.
