This example is somewhat of a conundrum, in that it has the smaller carbine muzzle ring, but according to production records, the serial number, 371430, is for a M1911 rifle that was produced in 1914.

The ridge near the base of the fuller was added to help retain the bayonet in it’s scabbard. Early examples, like the one above, had no ridge. Most of these were modified by placing a rivet in the fuller.

According to production records, the M1931 Short Rifle with serial number 648725 was produced in 1941.

The M1914 has a swell-point blade profile, where the blade is wider at the point than at the ricasso. The 1914 is fullered on only one side.

The M1914 was issued to only select troops.  When issued with K31s the M1914 Pioneer bayonet was issued to:

- Engineers;
-Driver Corporals and mounted artillery Sergeants;
-Blacksmiths,  blacksmith Private First Classes or lance corporal, blacksmith Sergeants;
-Horse transport soldiers, PFCs, corporals and sergeants;
-Saddle makers; and,
- Drivers for Motorized Field Artillery, Howitzers and Heavy Howitzers.

According to production records, the M1911 Carbine with serial number 140144 was produced in 1926.

Made in 1917 by Saddler Fritz Pauli, Biberist, Solorthurn Canton, Switzerland.

Measures 7 3/8 inches (187 mm) long by 3 inches (76 mm) wide at the widest point. Carter classified this frog as #410.

As the low serial number suggests, this is an early example. The "W + F" mark indicates assembly by Waffenfabrik Bern, while "Victoria Schwyz" identifies the blade supplier as the firm, Victorinox, located in the Canton of Schwyz.

The scabbard has the leather tab for securing in the Schmidt-Rubin belt frog. Most early scabbards had the tab removed when the Swiss changed over to the button-style frog commonly associated with the Stgw. 57 bayonet. The scabbard tip is also more angular than the later scabbards.

To avoid conflict, the Swiss government gives half of the military knife & bayonet blade production quota to Wenger and half to Victorinox.

The later scabbards had a more rounded tip.

A later example, with the simplified blade marking. "W" above the serial number identifying the blade supplier as Wenger.

Made in 1989 by A. Bucher, Wolhusen.

Measures 7.25 in (185 mm.) long x 2.5 in (65 mm.) wide. Carter classified this frog as #588.

This example was made by the textiles firm of Werner Fasler, Tramstrasse 5, 5034 Suhr.

The frog measures 7.625 in. (194 mm.) long by 2.25 in. (57 mm.) wide. Carter classified this frog as #589.

The socket diameter shown at right is measured at the front. The socket diameter at the rear is .870 in (22 mm.). Most western assault rifles today have 22 mm. flash hiders to allow firing of the NATO-standard 22 mm. rifle grenades.

The 530 was S.I.G.'s first 5.56 x 45 mm. rifle, developed during the late 1960s. It was a very costly weapon and was never purchased in quantity by any military organization. The 530 gave rise to the 540 and 542 models, which were more affordable.

MANURHIN (Manufacture de Machines du Haut Rhin), Mulhouse, Vichy in France licensed and produced the 540 and 542 as an interim infantry weapon in the 1980s, until the FAMAS rifle was available in sufficient numbers. The 540 was also produced in Portugal and Chile.

Since these bayonets are devoid of markings, it is not possible to determine whether this example was made in France or Switzerland.
