It was a sequence consisting of a letter followed by two digits, starting with A10, followed by A11 and so on until A99. Here’s a table of the codes and their manufacturing dates: For example, H7634 is the thirty-fourth frame or fork scheduled during August of 1976.
Prior to this time, only special team tandems (like Olympic bikes) were made.
Serial Numbering: The first phase started in early 1969 and continued to the middle of 1970.
It consisted of the following fields: For example E69PT109 was a Paramount Tandem built in May of ’69. The second phase started in Mid-1970 when Schwinn started using the standard numbering system (and probably a common bottom bracket) with the company’s mass production.
For example, FF018524 was built in June of 1970, serial number 018524.
The Earliest Paramount Serial Numbers The very first Paramounts seemed to have had serial numbers starting with “A” followed by two or three digits.
This seems to have been a system started by Emil Wastyn.
We found a very early Paramount – claimed to be a 1938-9 vintage – with serial number A545.
Little is known about serial numbers for bikes built after World War II.
Unfortunately, an office fire in 1948 destroyed the Paramount records.
Numbers mostly followed a three-digit format – often but not necessarily with a “P” as the prefix.
By early 1959, serial number 949 had been reached, necessitating a new system.
The “New” System This system was used from Spring of 1959 to the end of 1965.
