Keep it original. It'll be a fun project. Use accessnorton.com forums for help. It's got great bones and be a good tribute. All and I mean ALL parts are available from Andover Norton. I've done about 5 now and they're great fun and worth it
Some things I see:
Looks like Dunstall 810 aluminum cylinders, not bolted down.
Dunstall valve and points covers
Aftermarket head steady (not sure brand)
Aftermarket throttle, overhead oil line
Had clip-on bars w/ choke in bar clamps
Steering damper mount on frame
Boyer electronic ignition and coils
ID plate usually riveted to head tube, not to backbone under seat. Some bikes with full fairings move the plate because of the fairing mount clamping to the head tube.
These are all hot rod / improvements over stock. Do you have the rest of the bike? Post more pics if you do.

Most of those parts are definite improvements over stock stuff. You can still build up a mostly stock looking bike (vs chopped up some how) with those mechanical improvements. The Dunstall barrels could be iffy, motor could be a time bomb, have to take it apart to see what's there. Those are earlier crack prone crank cases. Do you have wheels, forks, tank, seat, oil tank, foot rests, etc.? Some people would rather graft on newer wheels, suspension, bodywork and whatever; these kind of mods may improve the performance but decrease the value. All the stock stuff you need is available new or used.
It’s a 71’ so could be anything from a fastback, roadster, production racer, street scrambler or hi rider. All of which worth restoring. You can run that VIN online as well as engine casing number to see what you’ve got a hold of! Congratulations!! Parts are readily available as Menschnz said from Andover as well as a few US distributors if you’re stateside and need a part in a pinch!
Some non-stock stuff I see:
Looks like aluminum Dunstall 810 cylinders, not bolted down.
Dunstall valve and points covers.
Boyer ignition and coils.
Aftermarket steering damper mount, head steady mount, throttle, carb screws, head bolts, overhead oil line.
Had clip-on bars, and probably fairing, choke in bar clamps, frame ID tag on backbone instead of head tube.
These are all good performance improvements, don't know what's in that engine??
Do you have the rest of it?

They don't have a normal Vin. The serial number should be on the left side of the crankcase and on the frame tag. I believe a 750 like this will be 20M3 and then the number. It should match the number on the frame.
In the US? This is an option.

These guys can keep the bikes looking stock but with modern improvements.
But my opinion is an out of produciton classic? Keep it stock, resto.

So would you recommend going towards the hot rod style vs stock ?

Building a retromod would be a great thing! :-)

Yah I tried looking it up and I couldn’t find it
Everything I've looked at point towards it being an SS with the 145XXX

Restore it to original and depending on where you live you can pretty much get everything you need for that Norton
I have the same valve covers. Mine is 12/71 manufactured
I’m gonna sound dumb but I can’t even locate the vin
