Just getting started on this long delayed build (receipt says 5 years). 2nd hand AMS coach now dismantled and work started on roof. Should be fun. The kit appears very well made, like other Rio Grande UK models. Might be asking a couple of questions, like - What does the interior of the cupola area look like and what clour should the interior be ? Testors Floquil Railroad colours paint - can normal enamel thinners be used ?al
