If you want a 20ga bolt, buy it.
The problem is not price, it's availability.
There were only 8,723 Glenfield 50s made in 20ga and they were made between 1966 and 1973 (no serial numbers prior to 1968).
The Glenfield 50G preceded the 50. 4,762 model 50Gs were made from 1961-1965.
The only other Marlin 20ga bolts were the 55 hunter made from 1957 to 1963, and the smooth bore 55G slug gun from 1961-1965.
They all take the same magazine.
If the checkering is not too deep, sand down the whole stock.
The wood is white birch with a nice light grain pattern.
If you want it dark, you can re-stain it walnut (or whatever) and seal it with semi-gloss polyurethane for a mar-resistant moisture-resistant finish.
Or you could just seal it with polyurethane and leave it light.
The dark blue metal contrasting against the white birch is very unusual.
I did that with a Glenfield 12ga, and the dark blue barrel and action, trigger guard, and Limbsaver butt pad with the light stock make a great looking combination.
I figured, it wasn't walnut, so why not?
I have a Marlin 55 Hunter 20ga in walnut. I re-did the stock with semi-gloss polyurethane and it is a truly beautiful stock/gun.

p.s. If you decide not to buy it, let me know.

 

I have one for sale

 

Thanks for the info, looking at it again tomorrow, may pull the trigger, not to many Marlin made shotguns around.

 

Hi all,

I am new here, but stumbled across this thread by accident. I have a Marlin 55, 20ga in what I would consider very good condition. I bought it a few years back on a whim, but I have only shot it a couple times as 20 ga is too small for what I need here in New Mexico. Anyway...it has been sitting in my gun safe for a few years. If anyone is interested, let me know. I can be reached at javerhoff@gmail.com.

Thanks,

Does the Model 50 20GA take 2 3/4 shot rounds?

 

Hello,

I have a Model 55. It has a clip and takes 2 3/4" shells.

12ga and 20ga mags have the same box, different "lip" angle.

The 2 3/4" rounds will fit in the 3" mags, just push them toward the back.

Very cool! Just picked one up at a local Gun Shop for $150.00 It is in very good shape and I really like the lighter color of the White Birch. When I saw the like new condition and the price I couldn't pass it up!

Sounds like a good buy!

 

Here is another question in regards to the Model 50. Since the magazine seems to be able to hold 2 3/4" shot rounds and also 3" rounds, is the firearm able to fire both sizes as well? Since there is no marking on the barrel (and I forgot to ask when I purchased the firearm) I just want to be 100% sure.

ok, i own an old glenfield model 50, 20 ga. it has a serial # 70203887. any idea of what year and why it has a serial #. i picked it up at a yardsale in a cloth sheeth. its in great condition. thanx

 

The Glenfield 50G (produced 1961-1965) & Glenfield 50 (produced 1966-1973) bolt-action shotguns were nearly identical.
In 1966, the 50G became the model 50 when Marlin lengthened the breach for 3-inch shells.
Marlin made 4,762 50Gs and 8,723 50s in the 20ga model.

Yours has a serial number because it was produced after 1968.
The serial number indicates it was probably manufactured in 1970.
In fine condition is worth about $100.
The stock is stained birch, and originally sold for $49.95 in 1970.

I'm a sucker for Marlin bolt action shotguns, and don't have a Glenfield 50 in 20ga.
Based on your description, if you get tired of looking at it,
I'll give you $125 plus shipping for it.

I am looking for a magazine of my Marlin 50 20 gauge. Can anyone point in a direction to find one? I have been watching Numrich gun parts for years, they have been sold out for years.
