I bought a very nice Belgian 12 guage double barreled shotgun from a guy who bought a bunch of
guns at an estate sale and didn't know what he had. It was marked on the barrel with the name of a gunsmith
Andreas Lauenroth--Budapest whom I assume sold the gun out of his shop. Markings
on the water table and barrel flats show that the manufacturer was Manufacture Liegeoise D'Armes a Feu.
So I've been trying to do research on it. I found a reprint
of their 1910 catalog and found the model in there. Recently I found an online
directory of Budapest from 1900 and found an entry for the gunsmith.

Nev (name) : Lauenroth Andreas
Foglalkozas (occupation) : puskamuves (gunsmith)
Kerulet (district) : IV.
Cím (address): vaczi u. 60.

First of all, anyone familiar enough with Budapest to tell me whether vaczi utca in district IV was a good place to have gun shop? Or has heard of this gunsmith?

Now here is the intriguing part. The shotgun has an engraved stock shield (a small metal plate, which is
usually engraved with the initials of the owner) this one has a five pointed crown below which are the initials DNGY with the D and Y kind of small and the N
and G large and entertwined. I am guessing the crown indicates royalty, any ideas on how to find whose initials these are? I'd be happy to send pictures.
