Salt Lake City, Utah - Soldier with Gun and Two Cartridge Belts - Mormon ?

Description

Interesting Subject for a Studio Portrait! I am assuming this is an example of a Mormon soldier in about 1910. He is wearing an embroidered shirt and his shoes/slippers have "puffy balls" on the toes. Note that there are two different cartridge belts - one looks to hold bullets and the other appears to hold shotgun shells. If you are familiar with this type of soldier and his dress I would welcome your  comments! Condition is at least very good with minimal corner wear. Stamp box indicates that this postcard dates from between 1904 - 1918, but since the postcard is a divided back card, it is narrowed to 1908 - 1918. Not mailed and clean on the front. Back is darkened due to age and does not detract from the overall condition.
Tracking with good packaging will be used. The shipping fee is simply to recover my costs.
