Hi KJClear30!
Congrats on a low number find!
Looking over your pics, there would be a lot to find to make the bike whole again. Front fender, carbs, rear rim, seat, side covers, instruments, bars and more appear to be incorrect. I suspect there is more that is incorrect, but I would need more photos.
Many of us here have restored bikes in far worse condition, so it can certainly be done. My question is what is your end goal? Do you want to own a restored sandcast or get maximum value out of the bike?
Restoring this bike to correct original condition will take a lot of time to find the right parts and, of course, a lot of effort to restore the bike well. I would guess at least $25,000 if done right. A low three digit bike expertly restored is probably worth around $35,000 or $40,000. Maybe more maybe less of course
If the goal is to own an early sandcast, then you are well on your way. Who cares about money in this scenario right?
I think the major challenge will be to track down the correct parts. Correct guages, double-cut front fender, rolled rim and other parts are tough to find. It will take time.
