I am trying to find out what year a certain serial number was produced. It is an Inland M1 Carbine in the 5 million range. Any information would be greatly appreciated. Serial numbers of the Inland M1 carbine actions made during this period ranged from 70,000 - 950,000, and many of these actions were put into M1A1 stocks. Consistent features of the carbines in this range included a two-rivet handguard, narrow barrel band, flip rear sight, and push-button safety. M1A1 Serial Numbers Inland Manufacturing Division of General Motors was the only manufacturer of the M1A1 and manufactured approximately 140,000 by the close of the war. The M1A1 was manufactured in two main production runs, both of approximately 70,000. The first was produced and delivered from late 1942 through until October 1943.

Understanding the Meaning of 'Date of Manufacture'

The ATF Definition used in the AFMER Reports

ATF files a yearly report to U.S. Congress on the number of firearms manufactured by each manufacturer. This report is called the Annual Firearms Manufacture & Export Report (AFMER). This report states, 'For the purpose of this report only, 'Production' is defined as firearms, including separate frames or receivers, actions or barreled actions, manufactured and disposed of in commerce during the calendar year.' The phrase 'manufactured and disposed of in commerce' infers everything was manufactured and sold within the same calendar year, which is rarely the case in manufacturing.

All parts of a carbine, and all other firearms, are manufactured separately and completed at different times. When all of the parts are assembled into a functioning firearm ready to be sold, the date of manufacture of the firearm is usually the first day it is ready to be sold.

None of the companies that have used the Iver Johnson name have provided any of the information you see on this entire website, this page included.

Reconstruction of the dates of manufacture has been based on the history of the company, markings on the receivers, the firearm's serial number and the AFMER reports. Collecting and analyzing the serial numbers and their markings has been an ongoing process for many years. What's offered here may change slightly as more information becomes available.

The Charts

Since the two letter prefix that starts each serial number was based on the model and various models were manufactured concurrently, each two letter prefix has it's own chart showing that particular prefix's dates of manufacture.

Never say Never, Never say Always

Production is not Perfection

(especially in the months prior to a bankruptcy)

Rather than guess a specific year for a specific serial number the charts below present a serial number range and the years that range started and ended based on the markings and additional resources. Most charts narrow the time frame to within a period of 4 years or less. Conclusions as to the specific year within the time frame a particular number was manufactured are left for the reader to decide.

These were receivers with the New Jersey markings and AA prefix absent the serial numbers left over from New Jersey. Serial numbers were added by Jacksonville, AR in 1986. Jacksonville, AR selected these randomly for use as Enforcer receivers and added the E prior to the AA to signify the Enforcer model. The numbers should not be viewed as a sequence. These were built into Enforcers in the months preceding Chapter 11 Bankruptcy in October 1986.
