MrY,
I'm not sure if it's a '72 or not but the rear-keyed gas cap sez it's somewhere in the low '70s.
The serial # will tell you for sure.
You got this thing delivered and ridden it yet?
The photos tell me that when the dreaded PO cropped the front fender and installed the over-length fork tubes he transposed the fork sliders which got the front wheel in backwards.
This means amongst other things that the speedo will not show the speed and the odometer will roll backwards.
It's an easy fix. Take the brake lever off the bars so you can maneuver it without needing to open and re-bleed the brake hydraulics and undo the speedo cable.
Jack the bike up high enough that the fork tubes will pull out underneath.
Loosen the triple tree clamping bolts.
Slide the complete fork, fender and wheel assembly down and out of the 'trees.
Turn it all 180º and reassemble.
You can fix the extreme heavy steering that comes with extended forks at zero expense by removing the bars and sliding the fork tubes up through the 'trees so they look like goal posts.
OK, you're gonna swap out those ugly bars anyway so replacement bars is cost-neutral. Buying 'bar rearsets so that the bars will clear the upper ends of the fork tubes will be an extra cost.
Alternatively, save the rearsets cost and buy clip-on bars instead of ordinary bars and put them on the top ends of the fork tubes.
