For me it was first time on visiting that level shows and I expected a little bit more items and sellers with picklehaubes and related with it items. However found for my collection new items anyway.
I do understand what you mean,
There are several aspects to this: first of all: I like first world war militaria, in my eyes there is a lot of junk out there, but a person looking for a specific item to complete his willy's jeep, might have a very different opinion on " junk" and will scarcely notice the " hauben" .
I think there are a lot of beautiful items out there, although they only represent a tiny part of the material displayed, so you do have to look for them. .
There is a second aspect worth mentioning especially when you're new to the field:
a lot of dealers don't visit these shows anymore as trading is moved to internet mostly, but in my humble opinion seeing the real thing (and be able to touch and smell it) really adds a lot, when I see an item I immediately have a hunch considering its originality, second comes the cognitive aspect of studying the item carefully in search of red flags. But first impression remains crucial, and is better when the object is really there.
like everybody nowadays I also buy from internet, but you really learn the most by studying the objects in real life,
sometimes the photo's on internet don't represent the object exactly, I've been surprised both positively and negatively when an object arrived after buying it on internet. (there is a huge difference in the quality of photo's, those on the site of bertrand Malraux are the best, I don't like the quality photo's on the rittmeister).
Thirdly there is the fun of "treasure hunting", finding real treasures you were not looking for!!,Today I really liked the saxon Uhlan Tschapka, seen on one of the photo's, it was not perfect, (some disabilities, but genuine saxon corpus, wappen and feldzeichen, cocarde) thus genuine and very cheap, (as I promised my wife I did not spend money today, but I'm glad the tschapka was bought by a nice guy, I know, who had an enormous bargain.
So do visit the shows and study the objects displayed carefully, also when you are not interested in buying them, you learn from it.
