I inherited a Model 37 from my grandfather. It was his carry gun after he was promoted to Detective.
SN 739Jxx Would love to know around the time this gun was made and any other info someone can give.
The Model 37 was introduced in 1951 as the Chiefs Special Airweight prior to the introduction of model numbering in 1957. It's essentially the alloy-frame version of the Model 36. Yours dates from the 1971-72 so-called "wandering J" period - the "J" appeared in different locations within the serial number - just prior to then, and for the next decade or so after, it was always the first character. Production ended in 2006.
