1986
Submit the serial number to the company, or ask the expert at a local gunshop.
The Iver Johnson web site has some info
The Iver Johnson New Trailsman was made between 1985-1991.That is the best that I can do.The serial numbers per year of production are not available in the public domain.
Bill Goforth is the absolute authority on the Iver Johnson revolvers. He can be found on various gun forums such as antiqueguns.com . I rarely defer questions, but on H&R or Iver Johnson Bill has me beat hands down. sales@countrygunsmith.net
1932-1947
All that I can say is the Iver Johnson Model 1900 was made from 1900-1941.The Model 1900 Target small frame from 1925-1928,and the large frame model 1900 Target from 1921-1941.I do not know if Iver Johnson kept records of serial number by year?With a serial number that low,I would safely assume that it was made in the first 4 years of production.1900-1904.
The serial number is hidden on the frame under the grip. Removal of the grips will expose the s/n of you gun,then it can be dated. A great source of information on Iver Johnson firearms is The book "Iver-Johnson Arms & Cycle Works Firearms 1871-1993" by W. Goforth
the Iver Johnson website has some sn info IIRC
Not a lot of serial number data out there for these revolvers. There were made as a "lower price" arm by the Iver Johnson Company from ABOUT 1910 to ABOUT 1940.
