Mazda Pop Pack full view (unrestored)

This is possibly as rare as a 8' grey sided Pop Pack can get. Until seeing this, i had never seen a Mazda Pop pack before. I'm reliably informed that the blue writing makes this fitting even rarer.
The fitting here came from a building which had in recent times become derelict and open to the elements. It was one of many 8' fittings of the same type, single and twin tube, slowly beginning to rust as the building began to deteriorate. The building has since been demolished, but not before a fellow collector rescued a small handful of these fittings. They very generously let me have one of these super rare fittings, so many many thanks go to them.
Here you see the fitting unrestored. The years of grime and soot are very evident here. Just two hours later, all this was gone.
