ccc - Delauney - Belleville

I needed to find out what make of car has the round bonnet, my notes don't mention it.
Ahh - Delauney-Belleville . a French prestige car.

I think this may be a 1911 HB4 with a fully enclosed touring body.
Reg. LF 4109.
Usually sold as a powered chassis, allowing the owner to specify the coach-built bodywork.
