O Gauge Coaches, WLR Set of 4.

Hello, need some help trying to identifying these. Found a set of four wheeled coaches, light brown colour with Gold detail "WLR" and coach numbers

Set of 4
2 Brakes with elevated ends. 
1 3rd Class
1 mixed 1st / 3rd Class. 

Pictures below and would welcome any comments to help identify them, certainly kit built, metal is very heavy so not Brass, lovely detail all over but box is clearly just to keep them in has no markings or identifying detail. 

Thanks for your help...
