It looks like it could be one if those "Woodsman" models made by Royal Enfield and imported into the States and sold under the "Indian" badge. Basically, they were the Bullet 500 in a trials or mixed-surfaces-riding trim. I believe that high pipe may have been an option. There was also a very similar "Westerner" off-road competition magneto-only model, but I believe it had no lighting, and one can sort of make out headlamp ears and of course a brake light in your photo.
Shame that one cannot really make out the badge on the timing case, which would banish all doubt. But I'm sure someone more knowledgeable on these '50s breeds will be along directly.
There was a fulsome thread here on these beasties awhile back commencing at
