I purchased a Jungle Carbine a few months ago and have been trying to figure out what the painted "603" on the buttstock refers to. Do the numbers correspond to an infantry regiment or something else? If the numbers are an infantry, is there any way to pinpoint where the rifle was used in service at?
Here are a few photos...
