Answer
Good Evening, Michael.  Old B.B/Airguns are special and extremely interesting.  As you are finding out, there is a wide variety of them with Crosman and Benjamin being two of the main producers, but behind the DAISY
Company, who are the World's largest producers of air guns.

To answer your questions, however, I am going to have to have additional information on both of your guns.
Since you mention the Benjamim Franklin, first, let's start with it.  

You have said that it is a "Bolt Action, Single Shot, Pump".  While it is possible for it to be a b.b gun, I sup-
pose, I suspect it is actually a "Pellet" gun.  There should be a model number stamped on it - somewhere.  And it may simply be a number, like "312",
stamped on the round breach END of the receiver - right above the wood stock.  Or, it may be located under the Benjamin name on the TOP of the gun.  I NEED THIS NUMBER (or name) TO GIVE YOU THE INFORMATION YOU SEEK ON THIS GUN!   Okay?

Now, for the Crosman:

The V350 - Mfg. 1961 - 1969  

Crosman touted it as: "Here's the World's First Air Rifle that has Everything BB Shooters have always wanted!"

Originally claimed to have a velocity of 350 fps., and very accurate for a b.b gun.

Still a popular model for people liking to shoot the old models.

In 1966 - 67, Crosman took the basic V350 and added more wood to the stock (on top of the barrel) and other embelishments to make it look like and M-1 Carbine - retaining the curious "slide- Action" cocking method of "Slide back barrel to cock and load...slide forward...then shoot."

In 1968 - 76, they "upgraded"(?) to a plastic stock.

These brief descriptions should help you decide which guns you have - and with the added information, I will be able to give you a more complete description and history of your guns.

Look them over carefully,  perhaps with a magnifying glass, especially on the metal portions for stamped information as to Model Numbers and names.  Just like an automobile, there were many models of them, and many changes made as they went along.  I need all the information I can get!

Sincerely

Old Injun
