Hi, Anny,
I cannot help you directly with info for your Darracq, but maybe some advice. I also have Richard Blizzards book – a friend wanted a model truck for his kids that wasn’t made from plastic, so I built him the Scania truck in Richards book. This led to other things – I built Richards Landrover, but didn’t like it much, so designed my own. I found many pictures on the Internet, and enlarged these and scaled them to get dimensions – once I found a good picture, it wasn’t too hard.
It all got a bit out of hand – I am forbidden to build any more of these wooden models because there is no room for them in our house. I have posted some pictures in my album on this site – the SS100 is the latest, about 30cms long – it has wire spoked wheels, working steering, and the bonnet and hood can be opened/closed – I got the dimensions for this from a small metal model I was given. It is not 100% accurate, but makes a great model.
The bulldozer was built the same way. (I asked if this was of interest to ME, but was turned down – apparently wooden models, even if they ‘work’ are not ‘engineering’, and other editors didn’t even have the grace to reply to e-mails).
The helicopter was one of two built for another friends kids, also from Internet pictures. I simply look for a photo taken directly from the side, and also hopefully from the front or side, then use a graphics program on my computer to scale them up or down. I can then derive sizes of wheels and other parts of the car – at least close enough for a reasonably accurate model, as I hope my photos show.
If you are going to do more of these models, there is also a book called ‘Building Antique Model Cars in Wood’ by WIlliam Reeves (ISBN 1-895569-51-6. It has drawings and instructions for several antique cars (unfortunately not the Darracq). The finished sizes are a little smaller than Richard Blizzards models, but they can always be scaled.
It would be good to see a picture of the Rolls if you can post one.
