Start looking with these people. See the link Below.
Let me guess your Rifle is either a model 310, 312 or 317. It was made in 1965
I'm going to try to answer your question, but first I need to clarify something:You do mean Pellet gun not Pellet gum. You did not state the manufactures name so I think you mean "Benjamin 312 Pellet rifle."Now all you need to do is verify you meant "Benjamin 312 pellet rifle" and let me know the current condition of this rifle. Also state if it still holds air and is working condition.Then I can give you and estimate of value
T427432 was made in 1982.
I think you answered your own question. It's a combination BB and pellet rifle. I can add this information. It was made between 1969-86. It a pump rifle using the forearm as a pump. The name Benjamin Franklin was a marketing gimmick. Ben Franklin had nothing to do with it. Walter Benjamin started the company in 1899 and today it's owned by Crosman Corp.
Benjamin made a model 347 from 1969 to 1992 it was a pump handle that fired a single shot .177 pellet. As far as I know Benjamen never made a model 357 ( I may be wrong) but they have just come out with the Benjamin Rogue that fires a 357 caliber Pellet. This is PCP (PreCharged Pneumatic) class rifle. These are the most powerful class of air rifles today. The Rogue fires a 8 shot 357 caliber clip. The rifle cost around $1300. The 347 is designed for target and rodent control. The Rogue is designed for small to medium game hunting. The Rogue is not the largest caliber pellet rifle. Today the largest is the 50 caliber Dragon Claw air rifle by Sam Yang.
This Benjamin Model is part of 3 rifles that are in a series. The 340 is a .175 BB rifle. The model 347 is a .177 Caliber Pellet rifle and the 342 is a .22 caliber pellet rifle. this line of air rifles was made between 1969 to 1986 (Model 340) and 1969 - 1992 (models 347 & 342)
Never more than 10 pumps. I only use 8 pumps to be safe. More than 10 will damage the rifle over time.
