Hi Graham,
I just checked the instructions but the figures aren't listed...the instructions are in colour at least. I have the set but its buried in a box that I can't get to easily so please bear with me as I'll be doing this from partial instructions and from memory.
1. The steering wheel in the instructions is black, and from memory I think mine is. It sits pretty flat and has the 'sticky up bit' for the driver to hold.
2. I can't remember this but the only options for baby colour back then were white, red and yellow, and if I had to gamble on one I'd go red.
3. Yes, it's a white bobble hat.
4. Yes, the mattress was made of very thin foam which fitted perfectly in the bottom of the pram.
5. Mine doesn't have a moustache, just the beard.
6. The mans had is definitely light brown.
7. I'm pretty certain his cuffs are dark brown to match his trousers.
8. Yes, classic blonde hair.
Hope that helps for now
Claire
