I saw the pics before they were removed and can add, in my unprofessional opinion, its a darn good impression of a classic Lehigh. I particularly like the carving. For simple incise carving, the thick and thins in the right places, make for a refined and more sculpted feel. Not as crude as some folk art can be.
I too noticed the exaggerated arrow on the side plate. perhaps too heavy handed.
The geometry of this gun as a whole seems quite nice to my untrained eye.
