Hi there! These operators are very old, but we should still be able to help. Starting with your first batch of photos, the best replacement option we have is our 39-027E. The 39-028E is the opposite side. Your old part isn't made anymore but these are the best options we have. You'll note that the wheel at the end of the arm is different on these, so you'll also need a 39-533 track to help it connect to the sash. Some alteration of the sill may be necessary as well, though I'm not sure. I've never personally used our hardware to replace your old part, but this is the best option we have. Look these parts over and see what you think. For your second batch of photos, see our 39-001 and 39-002. I feel confident that these will work for you. |
