I picked up this fascinating little 0-4-0T on eBay recently, very clearly a model of the famous B&O "Dockside" or "Little Joe" tank engines.
The seller, who got it from an estate sale, didn't know anything about it, as it bears no labels whatever. We figured it might have been hand-made, when a lucky Google search led me to some information that identies it as imported by International Model Products (IMP), around 1950. I'd never heard of the company, and had no clue that anybody was producing brass, scale models in 3-rail at that time!
This little guy has an electro-mechanical e-unit and a vertical, open-frame motor that drives the rear axle through an 18:1 gear ratio. After some basic cleaning, it runs surprisingly smoothly. Clearly it has a few cosmetic issues, but I plan to super-detail and paint it. The collector in me says I should preserve it as-is, but I'd rather it be the best-looking model possible. I've never done brass work before, so this should be a good learning project.
Does anybody here know anything about IMP, or this model in particular? Now I'm curious to know what else may be out there.
