Operators for mobile home

A home owner from Massachusetts says:
Good morning,
Needing new operators. Not sure if 39-050 or 39-256 is the one I need. Please let me know which is correct. Pictures are attached.
Thank you in advance.

Hello, Mike. Reviewing your photos, I feel our 39-050 operator may be the better option. However, we would like for you to take another look at both parts you mentioned and see which of the two is the closest match.
