KRax!

Good-looking one!

I believe it looks rather european... I have seen two or three Belgium made trumpets on ebay the last two years and they have had the same kind of basic design (wrap). But I do not know a single thing about belgian trumpet makers more than that there were a few. Anyway the hex valve caps are very similar to the ones used by Keilwerth. Remember, the distances Belgium - Netherlands - Germany are almost nothing.
