Dave:
These guns are generally Belgian or Germanic. They often have no identification as to maker's name. And often they represent the gunsmith's "final examination" for entry into that society's gunmaker's guild. A proof of craftsmanship if you will... or a "union card."
As such, they offer very good workmanship for the money. Since there is no "name" they command much lower prices compared to a comparable "name gun."
On the downside, some design aspects of these guns can be a bit "adventurous". But that is generally the exception rather than the rule.
