Kia Ora Richard,

Nice Brmms!  Just a note on the missing windscreen of the right-hand version.  All the four racers in this series had a change in windscreen style where it had a section that went under the driver who held the whole thing to the casting.   Also the number roundel was changed to a sticker and the helmets were silver for all racers instead of blue, red, green or yellow.

The different screens are more easily seen on these Ferraris.
