Second-hand, as the website says. Very second-hand, judging by the photo of the Met C&W Co. ones (4th photo down) - though they do appear to be all of the same type so they may have been sold off from Met's hire fleet rather than simply being old wagons for which the company was acting as broker. This photo (9th photo down) gives the best view of the ex-GER wagons, two of them, from which it's clear they are this antique type, dating back to the 1860s in design, if not necessarily construction. Plus of course there's the inevitable Midland wagon - not a D299 but a 3-plank dropside, D305, of 1880s vintage (Drg. 213). Rather more surprisingly, what I first assumed was a SER or LCDR covered goods wagon (Kentish van or van of Kent) is in fact lettered H&BR!
