Black-shanked douc was created in 1871.
Depends on if it is a rifle or pistol
There is no such coin. Canada did not have any coins over 50 cents in 1871.
Such a coin does not exist. The Royal Mint produced no Farthing coins in 1870 or 1871.
Actually, it was Johnson and Bye, the fore-runner of the Iver Johnson companies, 1871-1883.
You will have to contact H&R 1871 Inc. to find out.
value depends on overall condition...................
It's not easy to answer this question because Quackenbush produced several air pistols with the 1871 date. All of them hold a high value with at least 4 figures in the price. They can be anywhere from $1,100 to $5.500 depending on the current condition of the pistol. The Air Rifles started in 1876 and also hold a high value. My suggestion is go to a large book store and locate a book called "Blue book of airguns 10th edition" and look up the Quackenbust H.M. section.
