Weathering looks fine, possibly some rust streaks from hinges?

Wheels - look black in the photos and maybe ought to be grey covered with oily black sludge.

Hi WS,

Thanks for the compliment regarding the weathering, unfortunately I didn't provide any hinges to the doors which I now regret and might just add prior to the final varnishing.

In my next blog I'll be showing off my newly purchased 12v mini drill, with which, hopefully, I will be able to rout some slots out beside the doors to insert some scraps of brass in to represent hinges, and then some rust streaks as you suggest.

The rust patches on the strapping is done with an eye make up set I bought in the local supermarket, I got some strange looks from the women around the checkout. Sadly my Fench wasn't good enough to tell her it was for my hobby!!!  

The wheels have been weathered with the same colour as the underframe, you can just see this in the 2nd picture down, but I didn't paint the flanges because I didn't want to inhibit the free running, so that needs to be done. One ot the remaining job is to file back the brake shoes slightly as they bind very slightly on the 14mm wheels fitted.
