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.
Usually it's on the barrel close to the breech. Unless it's a really old Benjamin and then it may not have one.
