Impossible to answer at long distance. The value of ANY gun is based on exact make, model, and condition. In the case of your drilling, condition will play a very large factor in valuation. Sorry, but you are going to need an appraisal from someone that knows European firearms.
Requires professional appraisal
No there are ways, it invalves drilling holes to vent gas witch operates the gun.
Requires professional appraisl. Could be 100-10000 USD
To remove the ignition barrel you need to be able to turn the key to position II. On the barrel casing you are looking for a small hole in to which you insert something like an Allen Key. The barrel can then be extracted. If you can't turn to the second position then its time to get the drill out and carefully drill the contents of the barrel. It's worth tapping the casing with a hammer whilst turning the key if the barrel has stuck before drilling.
You will have to provide a detailed description of the action, ALL markings, barrel length, rifle caliber and finish.
Multiple barrel carburetors were used to give a more efficient fuel flow to an engine when compared to a single barrel. High powered engines have been known to have three two barrel carburetors, commonly called a six pack due to the six barrels being used.
i bought one from Calbulas i paid 3800 for it
Most arduino models (including the Arduino Deumillanove and the older Arduino NG), can be powered with either a USB cable connected to a computer or with a 9v battery that is wired up to a 2.1mm barrel-tp male plug.
Although I know of no "three-barrel shotguns", it is entirely possible that someone, somewhere, sometime made one. However, there is a type of long-gun commonly referred to as a "drilling", which is probably best described as a side-by-side shotgun with a third barrel located centrally below the two smoothbores. This third barrel is usually rifled, and is chambered for a .30" caliber or smaller rifle cartridge. "Drilling" is actually a mis-spelling of "dreilling", deriving from "drei", the German word for "three" and it is generally thought that this type of general hunting arm originated there. fenianmarksman
NO, not safely anyway. the black powder guns use a much larger barrel pivot pin that their firearm counterparts. to switch from the black powder to accept a 410 barrel you would have to drill out the pivot pin hole on the .410 barrel to accept the larger pin, the black powder barrel support arm is thicker, to account for this....the .410 barrel support arm will become to thin from the drilling making it prone to creak or break.... need anything leinad related? guns, parts, kits, pictures, advice? contact me. xthexheadx@gmail.com
The gun you describe is called a drilling. I would search www.gunbroker.com, auctionarms.com or gunsamerica.com for pricing.
The main reason is the revenue vs. cost-equation: oil prices have gone up between 1998 and today from $ 12 a barrel to around $ 100 a barrel. So the higher cost of drilling in remote, arctic or otherwise "difficult" places is easily offset by the much higher revenues.
