I cannot find any good reference image for the poppet valve gears! the fact that they are asymmetrical doesn’t help either. in fact i have gotten so desperate that I am even thinking about dumping $1200+ on a Lionel O scale t-1(because no blender model exists that I can find that has the poppet valve gear modeled correctly. and yeah I know high iron’s video about the duplex development has accurate valve gears but where do I find that model?)
