How can you find the date of manufacture for a Glenfield Marlin model 30 if you have the serial number?
By the serial number letter prefix. The Model 30 was introduced in 1964. A Y or Z prefix is for 1964. AA in 1965, AB in 66, etc.
What is the value and year made of a Glenfield 30 g model made by Marlin Firearm Company in North Haven Conn?
About 10-15% less than a Marlin 336 in similar condition. Not knowing what condition your gun is in, estimate from $50-$200. Year of manufacture is probably going to be in the 1970's, but without knowing the serial number nobody can tell. www.countrygunsmith.net *My Glenfield Model 30G with serial number AB481XX manufactured in 1966.
