I need the correct mortise lock for my door please!

Question

I searched the model # and found a forum on this site of someone with the same information, so I ordered the 82-218 Mortise Lock, Round Face 3-11/16". (Order # 1354721. I need to return this and get assistance ordering the right one if possible please.
This one seems to be the same size(roughly a quarter inch too big for the insert) as the one that Home Depot, Lowes, and Ace Hardware sell.

I don't have a picture of the original lock as it sadly fell into the door due to my rookie mistake of unscrewing it when trying to replace it.

Attached are both stickers on the door with model info, and measures of the insert and screw holes.

Thanks for posting. I'm actually very confident the 82-218 is what you need; the hole pattern and the handle set both match styles commonly seen with this mortise lock. The issue is you have to carefully insert the mortise at an angle, and it's a pretty snug fit. See the video below, and let me know if this helps.
