I've always been quite fond of the early days of steam, and I'm starting to get back into model railroading again and am looking for engines from the 1830s - 1860s or so. Patentees, Adlers, Cramptons, and the like. I can find no rolling stock, either. All I can find are a small number of 3D printing files, which are not an avenue I wish to pursue - I'd much rather purchase a complete unit. From what I can tell, it seems that most model railroaders categorize things into "eras", though the earliest seems to start long after the timeframe I'm looking for. Due to the extremely limited space available to me, I plan on my new layout being N scale. Have any of the many manufacturers around the world ever produced trains in that size? I feel like I've looked through all of them - every single one of them seem to have the exact same Hudson's and Pacific's, but nothing with a single driving wheel. Any advice?
