So the first one is a Pengun made to shoot tear gas canisters. It basically works like a simple zip gun with a spring loaded firing pin that locks in place. You simply load a canister with a rear primer and release the spring. Pretty cool pen and I'm told that they make flare cartridges as well. If anyone has a source for ammunition for this I would love to buy some (assuming it's legal). I'm told by a Marine NBC specialist that the tear gas canisters from this time period will not still activate properly.
The second is a Parker 51 with a 16k gold filled cap. It has initials and a last name enscribed on the barrel. My buddy cleaned it up and it functions flawlessly. I spent roughly an hour in research and believe I located the son of the original owner (the father has passed if I'm correct). I feel that it's only right to call him to see if he has an interest in having this pen (would arrange a trade or something for a similar model). My wife however thinks that it would be "creepy" to call him out of the blue and ask. Let me know your thoughts.
