Nice buy , don't see many in good nic.
I bought a few of these some years ago one being early mk1 ,followed by a mk 2 and a second mk1 .
I keep meaning to get them out for a 're lube and few shots.
Bought a cracking 335 in 177 from allsports in Gloucester that has had a pro tune with custom synthetic seal ,spring and guide that thing shoots fantastic .
Nice classics the 335 , enjoy
