Yes, spot on Ken, that's the Ranger.
Mike - Generally, until about 1950 we also use the first number of the serial to further date Bulova watches. Around 1950 there was a s/n system change. When there is discrepancy between movement date code and serial year we (generally) default to the newest of the two.
