One of my many weaknesses is picking up old copies of the Model Railway Journal on eBay if they have any articles which may be of use. Acquiring a clutch from 1990, there are some interesting letters advocating a correct scale for 5’3” modelling to allow use of proprietary track. Suggestions included 1:48 or 6mm. Indeed, no less a name than JIC Boyd joined the fray, with some illustrations of his 6mm scale Irish stock. Nor could he resist a pop at Cyril Fry and Drew Donaldson in his letter, finding their use of 7mm/32mm ‘visually unacceptable’. He also records measuring a CBSC wagon sunk on a bank in Waterford harbour!
Interestingly, and I copy @leslie10646in for info, he derides the GNRI as being of little interest - it’s much too ‘English’ !!
The MRJ issues are 37 and 39, btw. Rather depressingly the bundle included images of Martyn Welch’s Hursley. You think you are progressing as a modeller and you look at what he did….what a reality check!!
