Lots of cool , useful stuff in the model RR line of parts that's for sure . The problem I have , is that very few hobby shops carry them anymore ( cue the old guy rant ) , unlike 20 years ago when there were walls of awesome plastic / brass / white metal bits , and I can never judge the size from catalogue pictures / write up ,and always end up with stuff too big or too small, even with a copy of the Walthers model RR bible to flip through . If you ever do find a bricks & mortar store that stocks that stuff , keep giving them your money ….
