Hello everyone, first post here! I've run a lot of searches and turned up some useful info, however sadly many links are dead. To briefly describe what I'm doing; I'm designing a small collection of West Highland models for resin 3D printing for my own collection, in N gauge. I'm focusing on the 60s and early 70s when NB Type 2s were working the time. I'd like to add to the wagon designs I have completed with others to represent workings for the aluminium smelter and paper mill. However I'm having a tough time working out what rolling stock was in use, I have some leads but it's hard to pin down. I know that timber ran on ex-Conflat P "Timber P" wagons and I have designed a model of this which has come out very well. I have also started work in the LNER wooden alumina wagon as well as the later LNER steel alumina wagon, and BR PAB COVHOP. However I'm struggling with the following:
China clay - "Clayfits?" I've seen sources saying that these were 5 plank hyfit wagons with an end tipper door, sheeted when loaded. I can't find any photos or diagrams of a hyfit end tipper with a 10ft wheelbase, does anyone have details? The only end tipper China clay wagons I can find are the 9ft ones which apparently didn't go to Scotland, and the only other references I can find are to "Clayliner" trains, which don't appear to feature end tipper wagons.
Tank wagons - Would there have been caustic soda or china clay slurry going to Corpach in tanks of any kind?
Paper reels and aluminium ingots - I have some grainy photos showing what look like planked long wheelbase open wagons, carrying sheeted pulp or paper. These look like BR Pipe wagons to me, possibly the LNER derived design diagram 1/445? A 2015 edition of rail express that I found mentioned that these were also used for aluminium ingots, does anyone know whether they were in use from the Fort William smelter?
That's it for now, however the more I get to planning this, the more questions I end up with! Anyway here is a photo of the Class 29 and Timber P I printed and painted, to give you a flavour of how I would like to collection to look.
