Here is the ubiquitous British Railways 16 ton mineral wagon with 8 shoe brake gear. It is drawn full size so scale to suit your needs.
There are Ready-To-Run and kit versions available for the 16 Tonner, but none with the BR 8 shoe brake gear as far as I know.
I have done body versions with the early top door and without.
Enjoy
