Thanks for your post. I believe these are actually the 39-387 and 39-388; note how the link arm (the part of the arm that connects to the sash) is riveted above the gear arm (the part of the arm that juts out of the operator body). Just make sure the link arm dimensions match. They seem to in the pictures, but photos of measuring tape are never totally reliable, so just double-check to confirm. Let me know if anything differs. The handedness of these operators is simply determined by what side of the base the spline that accepts the handle sits on. If the handle sits on the left side of the operator body, then you need the 39-387. If it's on the right side, as in your photos, then use the 39-388. Unfortunately these operators are no longer made with any other finishes. You could spray paint one if necessary, but note that modified products cannot be returned for refunds. Apologies for any inconvenience. |
