I've got a series of scale drawings of the 220mm gun from the original French manual - I can send those to you. I think I've got some vehicle dimensions somewhere. The Schneider engineers basically dropped most of the gun carriage into the SPG chassis - they sort of had to because the gun was a dual recoil system with an inclined ramp carrying the gun and hydraulic recoil/ pneumatic recuperator. The images of the SPG usually show the barrel pulled back on the carriage - the gun's breech was pretty close to where the crane on the SPG is when the barrel was in battery.
Regards,
Charlie
