BTW- I went through my files, and I found nothing similar to this camouflage scabbard. Most Sg98/05 were not painted at all, though some were, and most scabbards that were painted were the ersatz variations. They were usually green tones, and some were other color shades or black, but none were camo.
Of course this is but a small sampling, perhaps 1000 in all, as I do not save every bayonet encountered as there is little purpose to saving data on every 1915 Alex Coppel encountered when they are essentially identical. I only save data on variations or interesting features.
Anyway, you might review Carter's work on the variations, I peeked through my copies and saw nothing related, but I didn't go through the books in great detail. I also do not own his ersatz books, and they would probably be most revealing in this issue.
