Rob, Welcome to the house of fun.
Here's a suggestion. If you are willing to consider a subscription to Railway Modeller, Peco are bundling full access to the online Railway Modeller, all issues from 1949. On the assumptions that the review pages are included, and that Peco never failed to advertise their own product, that should get you pretty close to the release sequence?
ATB with your project.
Further thought, is anybody keeping a record of the current RTR OO antics? Since my resumption of OO railway modelling, happily brought about by the sudden emergence of RTR to a decent standard in the late 1990s, after which I largely stocked my layout first with Bachmann, then added some Hornby, then added some Heljan products: this mix of three brands persisting up to mid 2018; when the Rapido for NRM Stirling Single arrived.
Since when RTR OO items from Accurascale, Dapol, Hattons, and Oxford Rail have pitched up on my layout, and there's every prospect of a purchase from Sonic, while any of Cavalex, Kernow, KRM, RoS, Revolution and SLW have only to make something fitting my interest to win a purchase. (And while all the above was going on ViTrains and DJM appeared and evaporated too.)
