Still not sure Jonathan, the original early 1950s had a canvas bootlid, part of the roof, with an original angled back panel:

Then the bootlid was added ~1958:

Then later the back panel was replaced with the modern upright design.
So why were the clips ever added to the modern back panel when there never was a 2cv with canvas bootlid and an upright back panel. ??
Please someone out-geek me if there is an explanation.
I know what 2many is going to say - "Its Citroen, all bets are off <shrugs>"
Which is probably the best policy.
