Where can I get online information on proof marks of European shotguns?

In fact, I do understand some of the British proof marks i.e., London and Birmingham. But there arrives a confusion in identifying black powder and nitro proofs, chamber length and the change in proof marks from time to time. Further, there are entirely different Belgian, German, Italian and Spanish proof marks..?

Thanks for any information and links on web.

The older gun digest starting I belive in 66 did a differant country a year for 7 or 8 years. Yes each is differant and marks where change at differant times. But the gun digest info is a very good place to start. I have use it with good results on several guns.

The Belgian site above is good, and you might want to find The Book of Marks.
