One can get a rifle stock custom made in Dallas at a company called Beretta. There are many other locations across the United States as well such as New York City.
Someone could have custom posters made by Dallas Custom Made Products in Dallas. This is a company that not only makes posters custom, but all sorts of products also.
Made for the average shooter.
Any rifle chambered for that cartridge. Most will be custom made double rifles.
The stock and forearm were traditional wood, but can be other materials. With the AR15 and M16 rifle, they are made from metals and plastics.
Lock, stock and barrel
Winchester is one.
Depends how big the clip is. Stock clips I think hold 8. H&H clips hold 12. Not sure if the rifle itself chambers any behind the pin or not. The mag can be as big as you want it though, if you have it custom made.
There does NOT appear to be any current major producers offering a lever action rifle/carbine chambered for the .41 Magnum cartridge. There may be some custom made guns, finding a custom rifle gunsmith will require internet research.
