Marlin made millions of these rifles and unless it is a special edition it has no real collector value. To age a firearm you need to write to the manufacturer with the serial and model information. They are required by BATFE to keep these records. Whether they will share that information with you or not is another story. The good news is that most mfr's customer service departments will look it up and provide you a document with the information they have. They can even get as detailed as what distributor or FFL holder they sold it to after manufacture.

Could need a new spring in the magazine tube.
Ebay has complete inner magazine tubes.

Look on the roll mark on the barrel near the chamber end. You will find the model there. I am guessing it is a model 32. If it is an ocatagonal barrel pump action 22 lr caliber rifle it is a model 32 Marlin. If you are looking for the year it was manufactured, that is not the model is, like when talking about cars. Contact Marlin Firearms customer service (now part of Remington Arms) for date of manufacture.

No. built: 2.2 million (1922-2007)

The Model 36 was introduced in 1936 by Marlin Firearms as an improved version of the Model 1893. Around the time of the First World War, Marlin dropped the "18" and started calling the Model 1893, the Model 93. But no significant change in the gun's design took place. In the period between the wars, metalurgy was changing, as were manufacturing techniques. So Marlin upgraded the Model 93 and re-designated it the Model 1936. This moniker lasted only one year, and in 1937 it became the Model 36.
Model 36s were made until the Second World War. In 1948, the Model 36 was redesigned and modernized again and was given a round bolt to replace the square . The model number was again changed to Model 336. Lots of versions and lots of small changes have been made since, but variations of the Model 336 are still in production.
