Thought Wall's Gyrojet fires harpoon darts, it's not a Lancejet that looks different. Greg-Z (talk) 17:25, 7 August 2014 (EDT)
Another point about the Gyrojets, I do not think that the "pepperbox" is a genuine Gyrojet. Here is the only picture I can find of this variant, being help by the inventor Robert Mainhardt:Error creating thumbnail: File missingAs you can see the real variant did have 12 barrels an alothough similar, is definitely different to gun used in the movie. If nothing else, the vast majority of Gyrojet guns were chambered in 13mm or 12mm, and this gun has much smaller barrels. It is possible that it could be 6mm, but I think this was only used for a few dozen experimental assault rifles that were given to the US army so I doubt it is that. Also, it seems to have a needless amount of metal around the barrels with too much space between them. The real version has barrels made from very thin metal and were tightly packed together, which was possible due to the fact that it had an incredibly low chamber pressure. Also, just pointing out that pedantically this isn't a pepperbox pistol, but instead is a volley pistol. The difference is that a pepperbox has barrels which rotate on a centre axis to fire in sequence, as opposed to this which fires all barrels at the same time. --commando552 (talk) 09:31, 8 August 2014 (EDT)
Thank you, it's all seem reasonable. So I was too gullible when I found numerous statements about Gyrojet Pepperbox in Murderers' Row. So the screen gun is a pure fictional movie prop, right? Greg-Z (talk) 09:53, 8 August 2014 (EDT)
My guess is that it is a prop, but there is so little info about the various Gyrojets that I suppose it could be possible that it is a real prototype weapon. To me though, it has the look of a prop gun, looking a bit too simple and sleek, especially considering that these pistols were pure prototypes and were never produced (they were also only ever intended as a specialist military weapon for mowing down a pack of VC in one shot so I doubt they would look this "nice" for lack of a better term). Also, based on how the Gyrojets work, I imagine it is very difficult to actually get one to fire blanks (I have no idea how they manage it with the standard carbines and pistols in other movies, probably just a pyrotechnic in the barrel and no actual round at all), so it might actually be easier to just build a prop from scratch. --commando552 (talk) 10:35, 8 August 2014 (EDT)
I changed the description of this gun. Does it look correct now? Greg-Z (talk) 11:01, 8 August 2014 (EDT)
Thank you very, very much for doing a great piece on Murderers' Row. I believe Helm's AR-7 variation is a Hy Hunter Bolomauser, as the weapons in The Ambushers are Hunter AR-7 variants. I hope their are pieces on all the films in that great series.Foofbun (talk) 06:01, 8 August 2014 (EDT)
Well, I found out that I was wrong: Charter Arms started manufacturing of AR-7 only in 1973, so the screen gun cannot be Explorer II. But as Hy Hunter Bolomauser and Charter Arms Explorer II look just the same and both perfectly fit the screen gun, I think that we can keep the existing image with an addition that it's another but same looking gun. Thank you for clarification. Greg-Z (talk) 06:22, 8 August 2014 (EDT)
Thank you very much for your efforts to educate us. Enclosed is a piece from a magazine promoting You Only Live Twice that featured several concepts that did not make it to the completed film. The same magazine did a similiar piece on Thunderball showing a variety of interesting dart guns that weren't in the completed film.
My theory is both Irwin Allen and his former partner Cubby Broccoli (and Harry Saltzman) saw the 1966 piece in Life magazine on MBA and the Gyrojet weapons. Interesting how Murderers' Row beat YOLT to the post and also started the film with Matt Helm having a faked death and a trick cigarette. Also interesting how the Bond films of the '70s resembled the Helm films of the '60s (jokey villains, even the golden bullet on the poster of The Man with the Golden Gun resembling the "Matt Helm" bullet in the pre-credits sequence of The Silencers with Jaws meeting his demise in The Spy Who Loved Me in a similar manner to Ironhead in Murderers' Row.Foofbun (talk) 19:09, 8 August 2014 (EDT)
