Yes I'd strongly suggest this one has had a bit of component swapping going on.
Being that it's a single Ally ID plated chassis then I'd say it would have sported the Pentagon logo on both the Chain Case and also the original catcher. Maybe the chain case has been belted at some stage or had the cutter chain rub through the steel on the original due to lack of proper adjustment.
As far as pulling the roller halves apart, it seems you've achieved this as per your photos.
One thing that many haven't taken into consideration when vulcanising rubber onto the rear roller and is that it will increase the height of the chassis by about 5 mm off the cutting surface which is non adjustable and also changing the angle of attack of the bed knife to grass blades. It might not seem much but every mm changes how things function correctly.
Just a quick word on the rails, your machine looks like its survived rather well with minimal fatigue fractures, nonetheless I would utilise the Gusset repair method but I would increase the length of the gussets so as to help the torsional strength of the rails and push the stress out wider to where the chassis is stronger.

I live a 24 Hour lifestyle, but every now and again I seem to fall asleep, well at least that's what my wife tells me.
