When I was still a kid I bought a very Minty-looking #675 from Red Caboose in Manhattan. I opened my package on the LIRR to find the shiny paint was rubbing off on my hands... Shoe Polish!
I purchased a TMCC-equipped LIRR Camelback via E-Bay, but from a business in PA. They sent me the Conventional version. I sent it back. Within a week they ceased to exist.
