40c is this uc original

[hydrogeo]

So finally had some time to play around with my 40c over the holiday. It clearly is a mongrel, as it looks to have 420c tins and it appears to have once had an outside mount blade



The sprockets look pretty good but the tracks measure at100% wear. Here's a couple closeups






I drove the machine down the road and it tracked straight, and everything seems pretty tight. I'll probably just run it but I'm curious if the undercarriage was grafted on from something else. Anybody have any thoughts?

Those are 420 sprockets, and appears to be 420 rails as well, so definitely not original.

Thanks, Lavoy. Just want to make sure I know what I have.
