Unfortunately you did not state who made the model 312. Your question is incomplete and it is not possible to answer you. Currently there are over 50 different air gun manufactures.
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
Never more than 10 pumps. I only use 8 pumps to be safe. More than 10 will damage the rifle over time.
To get a Benjamin Franklin model 312 pellet rifle repaired, you can start by contacting the manufacturer, Crosman Corporation, for authorized service centers or warranty options. Local gun shops or specialty airgun retailers may also offer repair services or be able to recommend qualified technicians. Additionally, you can check online forums or communities dedicated to airgun enthusiasts for recommendations on skilled repair services.
I find two interesting points about this question. The Benjamin model 312 is part of the Benjamin 310 series of rifles 310, 312, 317 made between 1940 and 1969. If there is credit given why is it only on the .22 caliber version, and the second question is. Crosman didn't own Benjamin until 1992 so why would they give credit on such an old air rifle that they were not responsible for making. On Crosmans web site there is NO mention of any type of credit for this model.
Never heard of a 12 gauge rifle.
It was 312 CE.
Crosman owns Benjamin air rifles. they offer a service to locate repair shops the repair older Benjamin rifles See the link below
312 weeks is just under 6 years because a year has 52 weeks and 1 day in an ordinary year, and 52 weeks and 2 days in a leap year. 312 divided by 52 is 6.
He converted to Christianity in 312.
The 312 was part of a series (310 series) of rifles produced between 1940-1969. The name Benjamin Franklin was a marketing gimmick to help sell the rifle. Franklin had nothing to do with it. The series included the model 310, 312 and 317. Please state the current condition of the rifle to get an estimate of value. Is it still working? Is it in Poor, Fair, Good, Very Good or Excellent condition. Re-post you question with this information and I will try to give you an estimate of value. Make sure you put the question in the "Air gun and Air rifle" category.
6 years.. 52 weeks in a single year. So 6*52 = 312 weeks
