One of the earliest Finnish rebuilding programs was undertaken by the Civil Guard. The rifles were designated M24 and are the same basic pattern as the Russian M91. The funding for these rifles was raised by the Civil Guard Auxiliary known as the Lotta Svard and they are often known as “Lotta Rifles”. New barrels were purchased from the Swiss firm SIG and from three German firms. The SIG barrels are marked "Schweiz-Industrie Gesellschaft Neuhausen" on the right of the chamber above the woodline. The German barrels are marked "Bohler-Stahl" on the bottom of the barrel with no distinction between makers. All M24 barrels are undated and have the Civil Guard crest of an S topped with three fir sprigs in a shield on the chamber. All German barrels and the majority of Swiss barrels are heavier than the standard M91 barrel and have a "step" near the muzzle to accommodate a standard bayonet. The SIG unstepped, or "straight", barrels as pictured above are rare.

"Christmas Tree" on M24 barrel shank Meaning uncertain, possibly indicates barrel was shortened from rear and rechambered because of throat erosion

KLP and NSD marks are uncommon.

Variations
M24rv The Civil Guard cut down a small number of M24s to carbine length at the depot level to create the M24rv, which was patterned after the Army's M27rv. This picture is a digitally altered representation of this rare model. The overall length is 43 3/4" and it has an M28 type front sight.

Sights
M24s have the same type sights as the Russian Konovalov design of 1908.  The primary difference is the Finns remarked the rear sight bases in meters utilizing the existing notches.  Occasionally an extra notch is cut at the rear of the base and is marked 2 (200 meters).  Typically the numbers are placed on the right side of the base which was left blank by the Russians, but there are lots of variations in the manner of the numbering and how the existing Russian numbers were treated.

M24 front sight bases are integral to the barrel and identical to the Russian version.  However, the variation in blades is tremendous.   Many of them are pictured below with brief descriptions.
