This looks like one of those (seemingly rare) Scamps like the one that member "Robert W." has and was trying to identfy.
It has the same "tilt out" side windows
as the Love Bug
, a long door window, and then a three-part "tilt out" front window.
Partway through the thread I remembered that I had taken a photo of a Scamp
just like this (and, apparently, like his), but although it looked like a factory Scamp
, I could not be sure it wasn't some kind of mod. With these photos matching that one (and, it sounds like, matching Robert's) I'd say it must have been some kind of optional Scamp package (guessing late 70s or early 80s).
Here's a link to the aforementioned thread, in case anyone's interested; the photo I added was in post #18 in the thread:
