ok, everyone is right (but you know that already).
After measuring the windshields, I found all to be the same except
one, which I now know must have been a rogue that got into the
collection before I acquired it. It is very close in size to the P6,
but shorter by about 2 inches and a bit more squared. Fortunately for
me and anyone looking for a spare, you've all helped to avoid my
sending the mystery one off to some hapless fellow...
As usual, many thanks to the Rovernet.
