MASH (1972-1983)


M*A*S*H (or simply spelled as MASH) was the television adaptation of the 1970 film of the same name. As in the film, the series followed the antics of the medical personnel assigned to the 4077th Mobile Army Surgical Hospital during the Korean conflict in the 1950s. Though set during the Korean War, several of the episodes were meant as an allegory to the then ongoing war in Vietnam. The series aired on CBS for 11 seasons from 1972 to 1983 and its finale was one of the most viewed television programs in US television history. The series would also inspire two television spinoffs, Trapper John, M.D. and AfterM*A*S*H, although legally, Trapper John, M.D is considered a spinoff of only the film.

The following weapons were used in the series M*A*S*H:


Handguns

Star Model B

For the majority of the series, the Star Model B was used as a substitute for the M1911A1 that would be standard issue, since blank .45 ammo was more rare than 9mm at the time. It is used by many characters throughout the series, notably MAJ Frank Burns (Larry Linville) and Harry Morgan as both MG Bartford Hamilton Steele and as COL Sherman Potter. CPT Benjamin Franklin "Hawkeye" Pierce (Alan Alda) disdains guns, though he uses one in Episode 5.10 "Hawkeye, Get Your Gun" to scare Chinese forces. Burns has a Star Model B with pearl handles. As the comic foil, he frequently breaks every rule of gun safety in spades, despite being "regular Army".

Colt Commander

The Colt Commander is seen used by characters throughout the series, probably as a substitute for the regular Colt M1911 as the Colt Commander was not a common pistol seen during the Korean War. In the Episode 1.16 "The Ringbanger" Henry uses his service pistol. In the Episode 2.13 "Deal Me Out" Captain Halloran (Edward Winter) draws his service pistol because of gunfire in the camp (Winter would later become better known in the series as COL Flagg; a popular theory is it was Flagg using an alias). In the same episode, PVT Carter (John Ritter) threatens Frank in the shower.

M1911 Variant

LTG "Iron Guts" Kelly (James Gregory) carries two nickel plated M1911 with pearl grips as his sidearms in Ep. 3.04 "Iron Guts Kelly". This is most likely a reference to General Patton's Single Action Army and Smith & Wesson Registered Magnum, both of which were nickel-plated and, in this case, ivory gripped. On a side note, Patton himself reputedly hated pearl grips and even corrected reporters when asked about his "pearl-handled revolvers".

Colt Model 1908 Vest Pocket

In Episode 3.2 "Rainbow Bridge" Houlihan (Loretta Swit) gives Burns a Colt Model 1908 Vest Pocket with pearl grips for a concealed weapon before going to a wounded pickup in Chinese territory, in spite of the Chinese saying they were not even to have sidearms. Fortunately the Chinese are so amused by the diminutive size they laugh it off.

Colt New Service

In Episode 4.13 "The Gun" a wounded Colonel arrives at the 4077th with a revolver described as a chromed Colt .45, shiny barrel with bone grips, made in 1884. The year suggests that pistol is supposed to be a Colt Single Action Army, though the actual revolver is an anachronistic Colt New Service model, which wasn't introduced until 1898, 14 years later.

Frank shoots himself in the foot with it, which means that not only did he assume it was unloaded, but that Radar stored it loaded.

Smith & Wesson Model 19/66

COL Potter uses a Smith & Wesson snubnose as a starter revolver in Episode 6.10 "The M.A.S.H. Olympics." They alternate between the blued Model 19 and the stainless Model 66. This is anachronistic as the Combat Masterpiece, later renamed Model 19, was introduced in 1956, the snub nose version was introduced in 1967, and the Model 66 was introduced in 1971.

PPSh-41

Chinese soldiers in Episode 3.2 "Rainbow Bridge" are armed with Soviet PPSh-41 SMGs during the wounded pickup. If they were Chinese-made Type 50s, they would use stick magazines instead of drums, though North Korea did make licensed PPSh copies as Type 49s that only accepted drum magazines.

Rifles

M1 Carbine

Several US Army and UN soldiers are seen with M1 Carbines. CPL Maxwell Klinger (Jamie Farr) is seen with an M1 Carbine during patrol in a couple instances. During some Seasons Klinger carries only the M1 Carbine while in other seasons he carries either the M1 Carbine or the M1 Garand.

Valmet M71

In Episodes 6.12-13 "Comrades in Arms," North Korean patrols appear to be carrying Valmet M71 Sporter riles with synthetic furniture and the muzzle brake removed, to represent AK-47s. While this is likely a reference to the Vietnam War, any AK-47 variant used in the Korean War is an anachronism, since even the Soviet Union and China did not issue AK-type rifles until years after the Armistice was signed in 1953.

Shotguns

Double-Barreled Shotgun

MAJ Charles Emerson Winchester III (David Ogden Stiers) managed to get his shotgun sent from home for fowl hunting in Episode 8.12 "Dear Uncle Abdul." It's a hammerless break action side-by-side shotgun. As a nod to his character namesake (and affluence), it is possibly a Winchester Model 21 or 24 though the receiver is never clearly seen. MAJ Margaret Houlihan (Loretta Swit) borrows it during the episode.

Other

Mk 2 hand grenade

Mk 2 pineapple grenades are occasionally seen on passing GIs. Klinger threatens Father Mulcahy after a dispute with Frank Burns in Ep. 1.12 "Dear Dad". SSG Rizzo (G.W. Bailey) borrows a dummy grenade from PVT Igor to play pranks in Episode 11.15 "As Time Goes By." As another nod to the Vietnam War, these grenades are often painted black. Mk II grenades during the actual Korean War would be olive drab in color.

3"/23 caliber gun

The 4077th is supplied with a "40mm gun" in Episode 2.2 "5 O'Clock Charlie" when he starts trying to bomb an ammo dump near the hospital. This is actually a Navy 3"/23 caliber gun, similar to the one used in The Sand Pebbles.

M116 Pack Howitzer

In a poker game, Hawkeye wins a jeep from a supply sergeant in "Dear Comrade" (S7E11). However, when he is unable to procure a jeep, the supply sergeant instead delivers what appears to be an M116 pack howitzer. COL. Potter orders Hawkeye to remove it from the camp before it draws enemy fire, and even finds a number of artillery units willing to accept it. Hawkeye instead disables it so it can no longer be used, but does not actually remove it from the camp.
