All marks are in photos. I see 20810 on the piece that connects the bracket on the window to the elbow shaped part of the mechanism that attaches to the window frame. P30842 appears on that elbow shaped part. The window opens on the right, crank on left.
I took photos as I measured all pieces. I was not sure what parts you need dimensions for so please see photos for any dimensions.

Thanks so much for reaching out! This operator appears to be a match for our 39-031 and 39-032 operators. The sash bracket they connect to would be our 39-516 and 39-517, but this can be reused if you need it.
Please note that we cannot garner size from a photo of a tape measure. We have detailed dimensions for all of our parts that you can use as a point of reference.
