The cylinder left as is really does create a very nice transitional contrast between the polished brass & polished steel, also considering the brown grips which offset the brass. It's all very handsome and balanced looking.
The polish is great if they're going to be fired and even if they're not then it will help to preserve and protect them from fingerprints and humidity.
It's a labor of love, sort of like sharing what it feels like for a women to have a baby with the painful and aching fingers and all.
Congratulations on being the proud new father of...twins!!!!
