Not too flashy at all VK, in fact as modern day replicas and even original survivors go it's quite somber. My point on the other forum was that back in the day, they weren't all gaudily painted. Don't forget that these were built to provide a reliable working home to a family of five or more.
Small point on your model ...A Reading Vardo would have a taller, folding smoke stack, and being one of the bigger "Home" vans, it would probably be hauled by two or more ponies. The Roma rig would have extra ponies outboard of the main horse, which would often be a 'Shire or Wingfoot that was on a well desrved 'Holiday' from a farmer's plough.
PS: I've ordered the Vardo kit from the Russian Traditions website. Is this the one you,ve based your model on?
