🔹 What is the Marlin Glenfield 60?

The Glenfield Model 60 was a version of the Marlin 60 manufactured under the “Glenfield” name — a brand Marlin used primarily for rifles sold through department stores and hardware chains in the mid-20th century. Mechanically, it’s the same as the standard Marlin 60, but often featured different stock designs, simpler finishes, and more affordable pricing.

Despite its budget-market origin, the Glenfield 60 proved to be an extremely reliable, accurate, and well-made rifle — gaining a cult following among rimfire shooters and collectors alike.

🔹 What Does the “JM Stamp” Mean?

The “JM” stamp — usually located on the left side of the barrel near the receiver — stands for John Marlin, the founder of Marlin Firearms. This stamp identifies rifles that were manufactured by Marlin prior to the Remington acquisition in 2007–2008.

Why does this matter?

• Pre-Remington Marlins are known for their superior craftsmanship.
• Collectors seek out JM-stamped rifles for quality and heritage.
• They represent the “golden era” of Marlin production.

So when you find a JM-stamped Glenfield 60, especially as a police trade-in, you’re holding a genuine piece of gun history.
