saxser, Glen Torrence has a wonderfully scale 1/4 scale Dr1. I don't know the cost to ship to you but he does have a web site and you can contact him throught it.

Lucky Dog, I bought an instrument set from AZ a few years ago. I finally got around to finishing the plane and detailing the cockpit. Not all the instruments were usable (because of size and color) but several were and he does provide a good drawing of the panel layout. I think they are generic WW1 British instruments so they all did't work for my SE5a. Any way here is a pic of the near completed interior.
