I would say 1915; a model V judging by foot pegs, carb., and general options (or lack of.)
According to the catalog, the 2-3/4hp picked up the curved front fork shackles that year. Other features pin it to the 1914-15 year span. Possibly an optional 3-speed, judging by the length of the gear change gate.
In 1916, the rear brake block moved to the outside of the belt rim, so it can not be later than that.
