I've got a 1889 Marlin 44-40 that has a rough bore. The finish is red patina and rust for the most part.

I figure it isn't much of a collector so I'm thinking of rebarreling it. I have a new barrel and magazine tube to put on it and save the originals. I'll turn the barrel to half round half octaginal (my favorite) and put a short magazine on it.

Does anyone have drawings/ specifications on the thread pattern and shank of the barrel?

I have not found it in any of my books.

Any recomendations are appreciated.

Thanks.

You might try Numrich (www.e-gunparts.com)

Current Marlin barrels (for lever guns) are a square thread.

I'd guess you'll just have to pull the old barrel and make something that fits. Can't imagine there were any blueprints for that old design that have survived this long.... would be interesting to see how close it matches the current guns.

Yup, I guess it is time to go buy some "C" Channel. build a new barrel vise, and pull it apart.

I lost my old vice in a move about a year and a half ago. I needed a better one anyway.

Before I go pulling the barrel, does anyone know if the 1889 has any great collector value? This one has lost almost all color case hardening, has a patina on almost all metal, rounded barrel edges, buggered screws, faint, but legable markings on the barrel (44W) and Receiver (Marlin Safety). The bore is of course pretty much shot. Barrel length is around 28 to 30" if I remember correctly.

I'd hate to rip it apart then find out there were so few made that it was worth more than a couple hundred dollars.

Gimp - You might want to post the details of this rifle over on the Marlin Collectors forum, they may be able to give you a good idea about its value and whether to re-barrel it or not. CEJ

Could you give me a link to the Marlin Collectors Forum?

Thanks.

:D IMHO your '89 Marlin does not have collector value due to it's poor condition. Do what you like to it. Maybe a '94 bbl will work, or a new one. Not sure concerning the threads, though. Best luck with the peoject. Keep the forum posted with your results.

When you pull it, measure the threads, and I'll let you know if that looks like the same dimensions on a 336 barrel that I have lying around.

I finally pulled the barrel. It has a shank that is close to the 1895(?) Marlin. 12tpi square thread. I think it was 0.705 dia and 0.750 long. I'll try to remember to measure it again tonight and post it then.

It looks like the shank on teh 1895 does not have and extractor cut, at least in the drawings in the Gunsmith Manual I have at home.

Looks like I'll have to grind a square thread cutting tool.

If in fact a "poor" Grade most books list Around $150.00 value Specimines in good or better list at $1000.00 + as far as book value.

I just finished installing and fitting the barrel. I'm going to adapt a Lyman tang sight for the Marlin 336/30/1895 on the rear and a hooded post sight on the front. It doesn't feed properly, so I probably still have some slight fitting to do before I start working on the finish. It appears that it was originally blued, so I'll use a cold rust blue to refinish it. I'll test fire it before I blue it.

Since the barrel was actually a section of muzzle loading rifle barrel that I had laying around and had questionable rifling in it (0.006 double groove depth), I figured I'd test fire it before doing any finishing work.

I bore sighted it to get the sights close since I was installing a tang sight.

I went to the range today even though it was rainy and windy. There was a rifle match going on, but I was able to use an empty bench.

The target was a standard 100 yard rifle target with a couple of orange dots in the center as an aiming point. Bad choice. At 25 yards all I could see was black. The front post merged in with the black bull making it hard to sight.

First shot from a clean bore was low, outside the black in the 6 ring. The next four shots were about two inches higher all in the 9 ring. Three rounds formed a 0.9" group with the fourth shot opening it up to 2.2".
The vertical spread of the shots excluding the fouler was only.4" and the horizontal spread was 2.1".

The total group size including the fouler was: 2.8" Max, 2.2" Horizontal, 2.5" vertical. Not exactly precision shooting.

Considering the wind conditions and the sight/target problem, I'm pretty happy.

I think I'll forego doing any finishing work and just finish installing the magazine tube and make a perminant base for the sight. Thin I'll just shoot it for a while and eventually get a Green Mountain blank to make a proper barrel from.

That little 1889 with the steel but plate has a tad bit of a kick too!
