Ross bicycles from Allentown factory were usually on the non-driveside dropout or the bottom bracket. According to the catalogue the Paragon and Aristocrat models had forged dropouts, so it is unlikely that the serial number will be there. I have seen an Aristocrat model with the serial number on the bottom bracket.

The first two digits of the serial number are for the month of the year and the next two digits are for the year.
