Truth part 41012

Hello, thank you for posting,

Your operator resembles either the 39-438B and 39-439B or the 39-253LB and 39-253RB operators. The difference between these two styles is the guide at the end of the straight arm. Please review the video below that goes into more detail.

Also review the 39-451 and 39-452 or 39-375 and 39-376 cover/handles depending on style preference. Let us know if you have any additional questions.
