In my Gas Pump Identification book I have the 65 listed as first made in 1920. These type of pumps were going out of style, the visibles were the hot pump of the 1920s. By 1923 G&B were making clock face pumps. Clock face pumps were the rage of the decade, lasting to 1932 when Wayne Pump Co. introduced the first computer pump.
The first edition of the Blue Book which came out in 1942 does not list the 65 as being in production at that time. My feeling is that the pump was not made much after the late 1920s.
