I gave four of them a coat of flat brown yesterday - picture to follow.
Weathering to definitely follow. Toning down of the brown, perhaps dry brush with some greys and add dirt and grime.
I didn't make any of the single beets, this is the first railway kit that I have done. I found the chassis to be grand, I only had to trim the back off a few brake shoes where it was catching a wheel. I did however manage to put the brake gear on the wrong side of the wagon, despite the instructions clearly stating which way they should go.
Thanks for the pictures and video!
