Hi. What is this (ignore the paint, as it has probably been restored)? I got this several years ago from Europe. It was described as an M15, but appears to be made of thicker gauge steel than the standard M15. It is empty and has a hole punched in the side (under the lever in the photo). There were a few of these floating around a few years back and being sold on Ebay, so a batch of them must have been found somewhere. Cheers
