Good news indeed!! Keep us posted on the progress, you're adding knowledge to the database my friend.
One can pick up a Chinese clone, refurb it with good parts, and possibly have a bang up mini sniper rifle!!
Should I see if Gotha can get it for you?
Have you tried Pilkingtons for the part? They have a pretty substantial stash of parts available if you call them and inquire.

All my parts came in from Gotha today... The FWB cylinder and piston fit perfect in my BS4... Everything else matched up perfect like a factory fit... FWB parts fit like a glove in the BS4 receiver.
Too bad their special piston ring (with the overlap) was cracked during shipment. Ended up using my old BS4 ring.
