You know when a random subject starts a 'Google Trail'...
Starting with a search for Microplas get into all sorts of fabulous 50's designs including photos of the range advertised above in the mid 50's (Which in my opinion lends absolute authenticity to Gary's design concept) Take a look at their 'Toledo' on this link:
http://www.fairthorpescc.com/fscc_microplas.html
which could easily be a humpless, doored spyder with a bonnet bulge
Straying off subject here, their 'Microboat' would look great being trailed behind a Sammio spyder...
(btw, A company called microplas mouldings also makes Glow in the dark 'Sperm' keyrings
)
