The LNER Encyclopedia

At MOSI, Manchester, there's a 3-plank wagon painted in GC livery; a steward said that it came from Chatham Dockyard, and the body was a replica built at the museum. MOSI don't always seem to be accurate in their information (apparently, the Woodhead route was electrified because "passengers were gasping for breath in the tunnel", so nothing to do with lifting massive tonnages of coal over the Pennines then) but, curiously, it carries the painted number 2703 but a different number on the solebar plate.
At Quorn on the Great Central, there's a wagon in BR livery with a W prefix that doesn't look like anything that Swindon produced, but does look very LNER or LMS.
Any suggestions?

Interesting photo of the ex MS&L / GCR 3plk fixed side open. I've attached a photo of it whilst at Chatham..Doesn't look to have been rebodied !!, with its inverted V crown plates and its single wooden hand brake, looks to be a product of the 1880's. The livery ....well at least its got a coat of paint !!. The second photo shows a 7mm model of a drop side version, included to show the correct lettering ( yes I am aware that the tonnage is missing !!).
Cheers Tony

The van is undoubtedly of LNER provenance, though not necessarily used by the company. Some unfitted variants (equivalent to dia 171) were built for use in dockyards (? I think - certainly some sort of military or services connection), and consequently ended up in preservation. That said, the van in the pic looks to have a vac pipe, so may well be a 'genuine' railway company one.

Thanks for the info.
The vanfit had a "Met-Camm Midland Works, 1939" builder's plate, which looked original. This builder did not seem to be involved in production of LNER vans, but the year does suggest the possibility of a wartime need.
