I think the long running series in ME by Terrance Holland features a 5" one, started back in issue 4507

I'm afraid the series in ME Jason is referring to is on the narrow-gauge well tanks like Douglas. I haven't been able to track down any drawings of Overlord or the other WWII diesels. As far as models are concerned, Mercian offer a WD Barclay in 00 and 0, so I assume drawings have been available.

I think their main records are held by Glasgow University, but as they became Hunslet Barclay, the Statfold Barn Trust might also be worth a try. There may be a drawing in Tourret's "War Department Locomotives" or the combined volume "Allied Military Locomotives of the Second World War" but I haven't yet found a copy of either I can afford. I only want to build a gauge one model to go with the Woodbury Models Planet my son is waiting for (which we plan to build with the admiralty spec ballast weights, coal stove etc.), so if all else fails I will work from measurements and photos.
