Hello Gents,

The parts below were intended to be a AR45 project of mine but it never came to fruition. I'd still very much like to continue this project, but sadly other things like a new roof are in order. If you are interested in them as a whole I'll knock down the price quite a bit. I am negotiable just don't insult me please;)

If you'd like more pictures, let me know I'll be happy to take them!
