I have a tx200 MK1 turning up that needs tlc, though it won't be to the standard of this BSA restoration.

Its like restoring anything isnt it, you go as far as you want or dont want, my mate has an old webley a .177 i kind of slightly smaller vulcan with a metal at the rear hatsan style safety catch on it.
Just says webly on it nothing else, no idea if its Brumie or a turk.
Its Beautiful its lost its blacking almost from being loved but its been lightly oiled everytime it ever went out thats obvious, nice wood a few dings nothing you could not lift if you wanted the trigger is pure unadulterated Webly . i told him "Dont you dare farm up this gunLOL!"
He 100% agreed its for shooting its what its clearly done a heck of a lot of some body loved this gun its just obvious.

Averaging around 9.8 ft/lbs pre leading in (.177) Does that sound reasonable for a MK1 Airsporter S?

I have found that pellets that sit high in the tap give significantly more muzzle energy than ones that drop to the bottom leaving lots of lost volume behind them. Also the tightness of the o ring piston seal will affect m.e. I fitted mine with a Diana seal in the end to see if it would have a nicer shot cycle and be more accurate. It wasn't any better than the nicely fitting o ring I had on it previously. I think 9.8 is a good start. Cheers Max
 
I find O-ring seals take a while to polish up. At the start they are trying to grip the inside of the cylinder rather than slide. Get some lead through it and test after the first tin

I'm always biased towards shooting smoothly rather than squeezing out that last ft/lb

I'm happy with Airsporters at 9+
