Marlin 39A scope mounting holes

[LT.Diver]

I have a Marlin model 39A .22 lever gun. The serial number puts it in 1955. There are four small holes, drilled and tapped and filled with screws on the left side of the barrel. I'm assuming they are there to allow the mounting of a side-mount scope base. I'm just curious if this is something from the factory or whether it was done after-market.

My 39-A is from the mid 70s. It has TWO sets of holes drilled, tapped, and filled with tiny little screws.

One set is on the left side of the receiver, and allows the easy installation of a receiver sight. (I've got the Lyman sight on mine.)

The other pair of holes is on top of the receiver, and is for attaching the scope base which was supplied with the rifle.

There are no factory-drilled holes on the BARREL, just the receiver.

Apparently Marlin did, or at least would drill barrels for mounts.

I've seen several 1950's Marlin's with holes on the left side of the barrel that the owners SAID were done at the factory.

These older Marlin's were drilled on the tang for a tang sight, and on the receiver side for a receiver peep sight, but NOT on top of the receiver for a scope sight.

Personally, I suspect that most of these drilled barrels were done post factory.
