Larry, I'm going to bore you...sitting here fiddling sort of like Stan in rehabilitation. I looked everywhere on French sites for 50 cm, 2" chambered guns and haven't found any. But here's an interesting comment on www,Passionlachasse.com

Bonsoir Hunter59x,
Il est fort possible que ton copain ait raison et que son fusil soit chambré en 12/67. Cette histoire de longueurs de chambres me turlupinait d’autant plus qu’ici en Grande-Bretagne, un bon nombre de calibre 12 furent produits chambrés en 2” (soit 50mm) et certains armuriers étaient un peu fantaisites avec leurs chambrages...
J’ai jeté un coup d’oeil sur le site de « La canonnerie stéphanoise » et voici une vue d’écran de leur site avec les différents chambrages des divers calibres : pour le calibre 12 on y parle de chambres de 65, 67, 70, 76 et 89. Donc, je pense qu’on peut en déduire que le 12/67 est bel et bien un chambrage reconnu. J’ignorais aussi d’ailleurs l’existence d’un 28/76 et d’un 16/76, même si les douilles de 16 magnum ne doivent pas courir les rues...

rough translation: Good evening Hunter59x; its very possible that your friend was right and that your gun was chamber for 12 gauge 67mm. The history of the length of chamber bothers me much more here than in the UK. there a goodly number of 12 gauge guns were made chambered for 2" (i.e. 50mm) and some gunmakers were a little outrageous in their chambering..I checked out a site "la canonnerier stephanoise: and there was a view on the screen of their site a view with different chambers of difference gauges...for 12 gauge they spoke of chambers of65, 67, 70 76, 89...Thus I think that one can deduce that 12/67 is really a known chamber size. ...

I started looking at this site "la canonnerie stephanois": It's a company in Saint Etienne which repairs French guns. It occurs that they' might have information on what cartridges French guns were chambered for and when..and especially wonder if they have info on pre WWI French shells? .I'll get hold of them.
