Thanks for posting. I'm afraid I can't say for sure what you need based on these photos alone; a clearer view of the entire operator would be more definitive for identification. That said, look at our 39-013 and 39-014, or our 39-027E and 39-028E. Look over both sets of operators and let me know if one of these is what you need. |
