Maybe 1933-C. About the time that 26" balloon tires, (and later the super-balloons in 1933), the Snyder, Rollfast and Excelsior folks may have adopted a transitional one-size-fits-all frame design. It likely had some trade-offs, wrt how the bikes appearance seemed to fit either or both sizes of tires. I understand that the fork would merely be swapped 26, 28, as the customer ordered.
I generally associate the early alphabet codes (ABCDE) with Snyder's acquisition of Excelsior, and believe that the later end of the alphabet (WXYZ) indicates products that came from the Little Falls plant.
The badge holes look a bit narrow, and may fit a Montgomery Ward Hawthorne badge, (but the H chain ring sprocket is for DP Harris).
