There seems to be little rhyme or reason to a lot of the early serial numbers seen on Huffman bicycles.

Notice some of these numbering systems overlap years and may be specific to how the bike was branded for example the Firestone bikes.

1934-36 generally used five numbers.

Many but not all 1937 Firestone Fleetwood Supremes have a serial that starts with “H” followed by five numbers Ex: H10376
1937-1941 a letter followed by four or five numbers with, or without, one number below the other numbers is used. This seems to be more common after 1939.
