Not sure, I examined this under some fairly strange circumstances, lets say the lighting was pretty dim.
There were about 12 other daggers on the table as well, including an SS, RAD leader, the forestry blade which I posted in the forestry section, multiple Heer daggers, Lufts and a few bayonets.
I could get this NSKK for a very reasonable price, might have to bring a flashlight or something to view it properly.
I know the later chains were prone to corrosion & pitting unlike the earlier models, this one seems extra ratty though, just didn't have a solid feel.
Anyone know if there is a weight difference between the early chains and these later ones ?
