This painting/picture probably would have been done in the 1908-1913 range; but , possibly could have between 1919-1924. He waseither too young? or in the USA prior to '08 and back in the USA from '13 to '19.
Does any one have any insights on the uniform (army, I assume?), #17 on hat (regiment ?), the single stripe on sleeve equivalent to a Private?...Tips to acquire service records?.......Any clarity is appreciated. Thanks!!

Hopefully a little clearer close up of hat

Standard collar & shoulder designs?
