so in this video: https://youtu.be/4fELZGD0ED0 I commented about how I can’t find anything about poppet valve gears and that anything would be nice. the really frustrating thing is that I can find crystal clear diagrams of valve gears that I didn’t even know existed but can’t find jack about one of the most popular steam locomotives ever. to add insult to great injury I thought I found THE PATANT BUT IT JUST THE FRANKLIN POPPET VALVE NO GEAR! AHHHHH!!
