Hello there. This looks like either the 39-031 or 39-155 Dual-Arm Operator. The difference with these two operators is the length of the link arm. See the diagrams below. Measure it out to see which matches what you need. For a new handle and cover, see the 39-114L and 39-107 sold separately.

Dimensions for 39-031

Dimensions for 39-155
