Awesome! Congratulations!

You ever read Unintended Consequences?

How much per round? and if I may be so rude, what does a such a weapon run up in Canada?


Damn right its loaded, it makes a lousy club. -JW

The Treaty of Versailles that ended WWI severely limited Germanys ability to conduct research and development of military hardware. In order to circumvent this the German firm of Rheinmetall acquired a controlling interest in the Swiss firm of Solothurn. Solothurn developed some interesting small arms in the 1920’s and 30’s. The S18-1000 was their premium Ant-Tank rifle, semi automatic firing the 20 x 138B round. Commercial sales were disappointing and as an anti tank rifle she was obsolete before WWII started. These rifles did see limited use, mainly in North Africa. Many were sold as surplus into the US in the sixties for $189.50! now in the US they fetch $20-$30,000 and about half that in Canada.

She weights approx 120 lbs and is over 7 feet long. The cocking handle is a crank, two and a half turns are required to pull the breech block to the rear, the breech block is held to the rear by the sear and the crank reversed two and a half turns. When a loaded mag is inserted the breech block “thunders” forward and chambers a rd. She is equipped with a telescopic sight, the body of which is machined as part of the receiver and has back up iron sights.

I am looking for loaded ammo, empty cases, operators manual, original transit box, spare mags and muzzle brakes. I believe a few years ago Sarco listed spare mags as “door stops” any one care to part with one?

Both the Italians and the Swiss had a wheeled mount for this girl, one of them would make a good conversation piece.

Try to look unimportant. Your enemy might be low on ammo.

From my limited information I believe she fired a 20 mm AP projectile weighing 2,274 grains at 2,760 fps. Performance quoted was penetration of 1.5 inches of armor plate at 100 meters, and 1 inch at 500 meters with a 90 degree impact angle.

I can remember adds for these things in the late 50's. Came in a wooden case with snow skes that you could attach to the bi-pod,3 extra magazines and 100 rds of ammo. All for $400. Last time I looked the shells were about $50 each.
