"If I'm not mistaken, the difference in ammo required some visible differences around the breach"

yes of course but can you tell the difference bettween the early and later Schnieder breech externally? from what I can see its identical..both used an interrupted screw breech .. the later version had a De Bange obdurator an internal seal because of the bagged charges which would be cylindrical in any case....

check out the french pics particularly the crews..

In these pics you see the brass cases and the breech so an earlier model...

US manufactured guns would have straight shields but the AEF used French built guns anyway...

So effectively the same gun would work from 1915 on, the french were not very strict on uniform regs behind the lines as can be seen from the pics...

Great pictures of the crews. Lets have the French gun crews like the ones in these pictures. So often artillery sets have gun crews as though they are on parade in smart uniformed dress. I know the "button counters" may disagree but post 'Stalingrad set' realism should be considered. Give me a work like dress anyday!

Although I prefer late WW1 I would be grateful for any WW1 French crewed 155.

I am sure separate mini sets of either American or German WW2 artillery crew(especially the latter - although not my cup of tea!) for this artillery piece would sell especially if up to the standard of the German Stalingrad sets.

I see that the Australians also used the 9.2". We have already have an American gun crew so is it time to let the Aussies have a look in?. They also used the Mk VII howitzer so it would great not to have to get the scalpel to convent the Americans to Aussies.
