OK, so I need some clarification on these mountaineer/artillery swords. Something is bugging me about their classification. Case in point, the above models. These two are listed as mountaineer, yet their pattern is clearly DOCUMENTED as naval in Boarders Away (pg 87) and Boarders Away 2 (pg 189), so what gives? These ribbed iron hilts remain elusive to their exac use, but the two above even have GR on their blades, which is exactly what is found on the m1803 cutlass? Didn't the m1898 Mountaineer models come much later? Did I make a mistake and truly pass up on a naval iron-hilt? ( )I know Fagan & Co and Frederick's Sword catalogs aren't well- researched volumes, but for many years, they have been listing swords like the eBay one and the above as naval? Can anyone show the Mountaineer sword as pictured in the mentioned book? Perhaps these sword-types were re-issued after the Age of Sail, just as the French M1801 had it's bowl removed and issued to ground troops later in the century? Comments please!
