New to the sight has 1889 with 20" barrel

[darock]

I am new to the sight, but I have seen some knowledgeable peoples posts. I have an 1889 marlin with a 20" barrel. I know they made a few according to Brophy's book. this rifle is 70% blue. lumber is nice. It has been drilled for tang sight and the upper receiver is drilled and plugged The barrel is an obvious 38 caliber, I have not accurately slugged it. The Chamber however is too small for 38-40 ammo but, 38 special with long bullet and 357 magnum ammo feed and cycle perfectly. so is the bolt modified? I have not fired it yet. I am assuming it has been cut down and not chambered for the larger 38-40 cartridge. The barrel is correctly marked for this rifle and the serial number is 41168 so it is an early piece, too early for 38 special even. can someone shed some light? I have a couple dozen early marlin levers but this one is a real mystery.

Thanks in advance

Rob;

The old factory records show that serial number left the factory in late 1890 in .32-20 caliber. So your gun has been bored out and rechambered.
