Not sure if this should be under tanks or artillery.
An article, presumably translated from the French, has been circulated within the Gold Reef Scale Modellers' Club (Johannesburg) about the above-mentioned vehicle giving the history of the four FCM-built SPGs with 305 mm guns up to the destruction of two in 1940. Drawings are also included in the article. The author is the grandson of one of the final crew members and used his grandfather's diaries to plot the development and use of the weapon from the end of WWI into WWII
Anybody interested in reading about the French political machinations around these weapons and their development?
