Very nice work! I am currently doing the exact same kind of work on a 1” scale live steam 4-4-2 Atlantic (NNG). I recognized the components right away. Your brass Components are very nice looking compared to mine made from mild steel. Thanks for sharing. By the way retiring does not increase my free time to work on trains, or so it seems from my perspective. I still have to make time for trains. Train hobby work has to be mixed in with fixing leaking toilets and painting long over due projects around the house.
