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.
This rifle was made between 1961-1969. it's a variation of the Quackenbush model 7. unfortunately you did not state the condition of the rifle, so no estimate of value can be given. Re-post the question with the condition of the rifle. Poor, fair, good, very good, or excellent and I'll try to give it a value.
The value of a benjamin sheridan 392pa 5.5mm 22cal air rifle is $185
I know of NO Co-roman air rifle. Please provide more details. Do you mean Crosman 180 air rifle?
What condition is it in. That determines the value.
Quackenbush made firearms and air rifles. I'm guessing you are asking about an air rifle made by H.M. Quackenbush. If so, Then you will have to identify it and rate the condition first to get an answer. He made 5 different models that fall in this time period. I suggest you locate a book at a book store called "Bluebook of airguns 8th edition" or any other edition, and look up H.M. Quachenbush in the "Q" section. This should give you an answer. And Yes these air rifles are expensive and collectible. if its a firearm then any"Firearm Bluebook" will give you the information

Like all antiques the current condition of the Air rifle determines the value. If you want and answer, then rate it as Poor, Fair, Good, Very Good or Excellent.
