Fire Extinguisher Location

I’ve had a fire extinguisher rattling around inside the car for a while – just in case! Didn’t want it taking up space in the foot well as I’ve seen in other cars so have placed it behind the passenger seat. The seats do not adjust that far back so will not get in the way, still easy to get hold of and nicely hidden out of main site.
As my MGB has a single battery then there are no wires / pipes behind that panel.
