Rick,
The helmet is fine. Through no fault of the seller, he was given a completely inaccurate description from someone who claims to be "an expert" in Imperial German, (highly questionable). So it is not the seller that is at fault here, as people will generally believe what they are told to be accurate. What was humorous was the evaluator describing this as a ""classic officer's helmet" etc. It is absolutely not an officer's helmet, it is Mannschaften; it is not worth $2500, it is worth (give or take) about $1000 or so. The unit is also very vague, as this was worn by a few distinct units. here is a list, every unit that had a gilt Garde eagle wore this helmet. http://www.kaisersbunker.com/gtp/New/infantry1.htm The best part was the evaluator saying "as clearly shown by the "officer pattern" chinscales. As you will see by surfing this site, the chinscales are standard M91 pattern, NEVER worn by officer's with the exposed lug like this; only Mannschaften.
I suppose the moral of this is, for anyone selling or buying anything, don't always believe what any self-described "expert" will tell you. Turn over any rock and you will find someone who calls themselves an "expert". This forum has taught me, that you can learn something everyday in this hobby. No-one is an expert.
