Hello Nick.
They look great, thanks for taking the time to share.
Running numbers (from Southern Wagons Pictorial by Mike King) between 4051-4500, 4701-7000 and 9001-50, although it seems a few of those had lower rounded ends. I used a photo of 6627 for drawing the model.
I saw that you had ordered one of the open Ds, great stuff, I look forward to seeing how you get on with that. The real thing had curved W irons, I wonder if anyone will have a crack at representing these!
I will be doing an 1864 SER 8 ton coal wagon at some point, also used for general merchandise and lasted into SR days.
Cheers,
Eddie.
