I recently acquired this old lever action 22 and of course I field stripped it for cleaning. Turned the bolt upside down to shake out the firing pin and it dropped out...in two pieces. Well, I found a repo on ebay and it showed up today. Put it back together and loaded some rounds to check for function. It not only functioned well but it's pretty darn accurate. The gun came to me with a factory letter showing a ship date of May 24, 1903. The letter states Barrel: 24" Round. The odd thing is it has an octagon barrel. I don't know if the letter is wrong or the gun was sent back to Marlin for a barrel swap. I'm leaning towards a barrel replacement but I just don't know. The barrel has the old New Haven address. It's a great plinker/squirrel gun with straight stock and Marble's tang sight.
