HMCS Thetford Mines (K459) Canadian frigate kodachrome AAA gun LAC
In addition to her twin 4″/45 forward, Thetford Mines also carried six 20mm Oerlikons in two twin mounts — one seen here in another LAC Kodachrome– and two singles. Note the wavy lines on the Canadian lieutenant’s sleeve, denoting his status as a reserve officer. The running joke in Commonwealth Navies that used the practice was so that, when asked by an active officer why the braid was wavy, the reservist would answer, “Oh good heavens, so no one would mistake that this is my real job.”
