Hey Fran, I know it's not an A-250 or B, but I thought it would help corroborate with the A series anyway. Correct me if I'm wrong, but I believe these were #'d in sequence with the A-250, then they started new #'s with the B's. That would make sense, since only a few hundred of these were made.(Frow states on page 121 that 352 total sales, as of Dec. 31st 1914.
