Offered here is a U.S.-manufactured Mosin–Nagant M1891 rifle chambered in 7.62x54R, produced by Westinghouse Electric Company, later utilized and modified within the Finnish system.
This rifle represents a classic example of a U.S. contract M1891 that saw extended service life beyond Imperial Russia, with clear evidence of Finnish use and refurbishment.
The stock features an original Finnish Civil Guard (Suojeluskunta) “SK.Y” marked stock disk, indicating issue and use within the Finnish Civil Guard system. Rifles bearing these disks were typically assigned at the local or regional level and often saw long-term practical use.
The rifle is also marked with a “D” stamp, confirming that the chamber was modified to accept the Finnish D166 cartridge specification, a standard Finnish upgrade.
Additional Finnish characteristics include:
Rear sight modified to metric (meter-based) graduations
A visible Finnish stock repair (reinforcement splice) located on the left side beneath the receiver, as shown in the photos
Evidence of Finnish refurbishment and long-term service use
Mixed serial components consistent with Finnish or arsenal-level reconfiguration
The bore on this example is excellent, with strong, well-defined rifling and a bright interior, reflecting the practical maintenance typical of Finnish-used rifles.
Overall, this rifle represents a highly desirable combination of:
U.S. production (Westinghouse)
Finnish Civil Guard association (SK marked disk)
Finnish chamber upgrade (D mark)
Authentic Finnish stock repair
Strong mechanical condition and bore quality
