What Fork is this!?

Hey yall, just picked up a running 1982 CR480R for $100CAD. Cleared the airbox and exhaust of seeds from a mouse who made this bike its home as it sat between two grain silos for 10 years. Cleaned the carb of all varnish, changed oil, and it started in maybe 5 kicks (left side kick too!). I plan to build this bike into something that's a flash from the past with a few modern parts so it can run with the newer bikes and put up a fight. But I quickly realized these forks are not from this bike! They appear to be a conventional fork with a single piston front caliper. Any ideas where this may have come from?
Also on a related note, has anyone tried a fork conversion on this bike? I have a set of 48mm Showas off of a 2010 CRF250R that I swapped for longer KYB units. Would I be able to use the 2010 triple tree, brake, front wheel, and fork to get it to work on this bike? Obviously I expect to machine the steering head to accept the clamps but it's an idea I tossed around my head for a while now.
Any help would be appreciated! Once this is figured out I'm creating a build series going top to bottom repairing/refurbishing the entire bike.

Pretty common for the forks to be changed on 480's. The stock ones are very desirable for people who race 78-80 CR 's.

No idea on the fork. The rotor is 86 - 87 CR.

Unrelated, but I am cleaning my garage and ran across a bench-tested stator and flywheel for the 480. It needs a new home and can go for cheap.

On the subject of Honda forks picked up a complete 1981 Honda front end with the 41mm forks They are in a poor condition Is it worth spending money on them with the view of fitting them to a 78 to 80 Red Rocket which I hope to buy in the next year or so Will they make a great deal of difference compared to the standard 37mm ones in terms of performance?

Look like xr250 or 350 forks . 84 maybe?

I'll have to think on that. I haven't completed my teardown yet. Once I do I will get a better idea on what the old bike needs!

I feel even if it needs more work than you might have thought it would be worth it. For some reason people are infatuated with open bikes

Heres an 82 I built from a box o parts some years back as I didnt have an Ultima class vintage bike at the time, I think I have a kick starter and some triples from it around. Sold it back to the guy I got it from , it was his first mxer way back when. Fun motor with that classic 500 power but a little prone to stall in tight stuff, possibly a heavier flywheel would have helped.83 was better but this one was free so what the heck.
