WTS: U.S. M3 37mm AT Gun

Post by P.W.Browning » Sun Sep 13, 2020 12:30 pm

U.S. M3 37mm AT Gun
and accessories
$24,500
FOB: Hickory Flat, GA

This was purchased in the fall of 2011 off of the forum, and has simply turned out to be “a project too many” for me. This piece has fantastic potential, and I really hope to see it stay together and completed.

M4 Carriage is by York Safe & Lock and dated 1942. Fire Control Group needs to be assembled. There were a couple of missing original components that I had cast in iron off of originals but they still need final machining. There was no plunger cable as I received the gun, so a MB/GPW emergency break shielded cable is included as a donor. Hubs are of the MB/GPW wheel lug pattern. New solid MB rims and Coker Firestone “pie crust” tires have been installed. As with many M3 guns, the original sight assembly had been removed. I had a set of sight parts custom cast off of originals in either bronze or iron as appropriate. The final machining and assembly still needs to be done. I have a photocopy of the original sight base manual as well as numerous photos of sight base restorations I will supply the purchaser.

The Tube is the nicest original I have ever seen. It is a true M3 tube, with the slightly flared end and no threads. Chamber and bore show some use and age, but no signs of having ever been plugged, and no significant or deep pitting. Among the markings on the tube are are N. P. Co and 3-8-40.

The Breech Block and Ring are currently at my dealers in Smyrna, GA and can be transferred to any FFL as a Title 1 firearm. It was an original ring that had been assembled onto a live gun by Guiette Manufacturing in 1999, and is marked so in a period original style. The Block has a couple of missing components. I have never had it apart to pinpoint what is missing, but will provide photos if needed. Since this is not currently mated and registered as a live gun, you are able to pick up the gun immediately upon purchase, then transfer the ring to your FFL and start the Form 1 process.

Accessories include 3 original scopes (one a rare green painted “coated optics” example), an originally leather scope case, reproduction cleaning rod, original 10 gauge blank shell, 8 various original 37mm shells including shot, HE and AT all with reproduction packaging tubes, an original drill round, 4 NOS tow harnesses, and 2 gallons of TM9 Ordnance Paint, shade #8.

Hi Patrick I has had my M3 Gun for over 20 years Its a great little Gun and I have a 45 inch M2 50 Cal barrel turned down to fit . That makes it a lot cheeper to shoot. There.s a Video on Face book on reloading the 37mm Rds . Those Rds have a range of 12000 yards so make sure you have a good backstop. The AT Gun is a Hit in all parades and Military Vehicle Shows ! Just the right size ! Congratulations ! Don Shaffer N.E. Ohio

Do you have a link for this video for reloading? I am always interested if there is a new one. I have shot and reloaded for mine for a couple of years. Also always interested in buying any spare parts you may have?

Looks like the ring is a recent manufacture, is this correct?

I don’t believe so, just remarked when Guiette mated it to a tube back in 1999.

Perhaps board members Dan or Tony who this was purchased through could confirm.

If this was the cannon that Tony C had, it's a very nice one...

Thanks Jason, it is indeed.

I purchased it from Tony back in November 2012.

I’ve had a couple of questions about the sight base parts.

They were professionally cast by a foundry that had done restoration work for historical cannons. They need final machining, but done correctly should be the next best thing to an origInal.
