I think Keith had access to similar photos to what I received. My take is it certainly has the early instruments, 19 litre tank with early petcock, original front end, early triple tree and master cylinder, early exhaust spigots, a nice original set of 'lettuce-root' exhausts, has an early set of carbs with #28 caps to go. I'm seeing an incorrect seat, bars, RH switch, paint on tank, LH horn bracket looks to be broken away but there, 1 of the cables to the instruments, no indicators a side cover emblem, oil filter cover is finned, cracked air cleaner and a little bit of this and that but I would think this is as good as one could expect. It has the very early oil lines, early brake lines etc.
So what would you do with this bike
We know the motor is stuck but I would try the Aero Kroil remedy first. Maybe a deep clean of the frame, fix those items not original and see what the outcome is or would you do a complete rest.
