According to Baily Brower in his book "SAVAGE PISTOLS"
"All .32 caliber Model 1907's except the last 26,400- the finsal variation, 1907-19 Modification number 2 -- were fitted with a round burr-type cocking lever. The last group was fitted with a thin, spur-type cocking lever. This feature can cause confusion when identifying variations because a heavier spur-style cocking lever was a no-cost option for all Savage pistols starting in May 1914. Nonetheless, it remained a relatively rare feature until becoming stadard in 1919"
It appears you have a very nice special order cocking lever 1907 from 1914.
