Great pictures steve-I was looking thru the pics and thinking how good this ole boy was preserved until I got to the swing circle OUCH!! That's nasty looking! Good to here it will be repaired. The machine seems to be in good shape for it's age. Lot's of good diggin years left. Looks like you have enough info now for a lot of outside work.

I plugged some of the newly acquired dimensions into my master full size drawing of this machine and looks like I'm about as close to the real machine as I can get with my previous measurements and guesses.
I'll be starting the two outer walking shaft bearing towers first. I have some of it drawn up but need to do alot of detail work with the placement of the rivets and bolts.

That's a lot of bolts! But at least they've got nuts on them and won't need tapping. Looking forward to seeing more!

There sure are a bunch. I was thinking there were more riveted joints on the exterior but now I can see. I will probably tap most of the holes and then put a nut on some. That would make the joint less likely to come loose. That's easier for me because those tiny nuts are a real pain to screw on a loose bolt. Nuts do show better detail than just a bolt head.
