Tonight I got the engine out of the frame and onto the bench. I brushed off some of the gunk and found the engine number. With that discovery I had to know if the frame number matched. After some looking about I found it and I have matching numbers. Hurray!
Here are a few shots. Still a long way to go but I feel good about the progress I'm making so far. Nothing has been so stuck I needed a torch to remove it. I may need a torch to get the gunk off the cases but we'll see what some degreaser can do first.
