Just received my Marx 3/16" B&O gon. Nicely proportioned. Cute as it can be. Seems to be relatively clean. No real rust issues. Coupler springs in place and seem to work with light touch. In all: Good purchase.
Question: Do any of you clean the years of dirt film off your pieces? If so, what do you use so as not to damage the paint/litho work and how do you dry it to insure all the water is gone and thus doesn't become a rust producer?
