(related to old Dutch stapel, a pillar)
Anyway that’s what the Mark V SPC calls them. Two on the main body and two on the boot lid.
Although the saloon section doesn’t say so, the ones on the body have tapped plates welded on inside, and those for the boot lid have separate tapped plates, mentioned in the DHC section.
These are from my Mark V. Seem to be the same as for Mark IV near as I can tell.
I don’t find these staples in any of the '36-'48 parts books.
No tool tray insert either BTW, just the lid.
Here is what I have for the '38 SS main body. There is nothing inside the body to fasten these, just screw holes.
I’m thinking there is a fair load on them if used as luggage constraints, so they should have tapped plates for extra strength, rather than nuts and washers.
So does anyone else have tapped plates in there? Or just nuts and washers? Just reach under the edge of the boot opening and feel them.
