I feel ya Noelf, I can definitely see where you are coming from. But I have a Type 53 that is a hodge podge of parts, nothing matches. So I have been scared to crack it off. But I checked it with the gauges, and yep, it passes with flying colors, go figure. But for being all mismatched, its in beautiful shape, I've never seen a bore as good as that 53 on a Nagant. But please post more of your empty case and masking tape method for us.
