I know this is a really old post, but I'd love to see your Larrey ambulance and your link isn't working for me.
Edit: Ah, I was able to see the pictures on your blog though. Beautiful! I love the tarred canvas roof especially. And does the ladder lift up? Do you have pictures of when you were making it? I love Larrey, and I made a model of his ambulance too, but in 1:12.
