Late 1980s picked up the 303Brit.Rifle No.5Mk.1, the so called "Jungle Carbine". The most prominent markings are A4524 on the butt socket, bolt, and magazine. I've not taken her apart in recent years, so I can't specify other marks, but it has "fluting"(lightening cuts?) on the 19.5 in.(bolt face to tip of blast deflector) barrel, close to the rec., and "F" marks abound. When I got it, the stock had a high gloss varnish (stripped off long ago) and the finish was all over dark park. I know, pic's would help, but I am a Technosaur. Asking "Do I have a real No.5, or a civillian market mock-up." I know the name "Jungle Carbine" is largely a marketing tool used postwar, and must be amusing to Paras and Commandos who toted them in Europe. Thank you for any info-Semper Fi!
