Ultima Bug box

A freebie from Ultima were a couple of 'bug boxes'. A delightful little addition to the railway.  This is the first time I've attempted to make anything from brass etchings and they are really easy to fold. I've decided to make the roofline high so will need something at the ends to fill it in.

Now just to add a floor, seats paint and glazing. You may notice the red on the side of the folded coach. I may add white around the windows. Black or red for the ends?
