Response to Three.
I've picked up spare valve stems at Canadian Airgun Forum store, get a quote first on shipping and they may have more spare parts since they still have B50/51s in stock.
Did you get "the Book/bible" on tuning B50/51 already?
The spares I have are o-rings, valve stems and M.C. hammer springs and a variety of different weight and preload hammer spring guides and transfer ports, both are home made from Acetal.
I reduced the preload on the valve spring rather than change that spring out because the alternate was hard for me to source.
I also tapered the valve face to 5/16" to reduce force required to open it.
I had filter screen failure so I no longer have one but kept the screen body in place to secure the fill valve.
Of course since your previous owner went to the extent of changing the barrel I would assume that quality replacement parts are used throughout your rifle, my parts were acquired and made for home tuning my factory spec rifle.
