2-piper you are correct on the mis-wording. I too think all French guns experienced proof even though the politicians didn't think it too important but the makers realized the importance of proof, whether obligatory or voluntary, because the industry as a whole was at stake. Still no idea on the "Crown" over "V". What are the marks opposite the "Crown" over "V"s on right tube flats and what are the marks just forward of the flats on the tubes near the lower rib?

Kind Regards,
