Believe it or not one even has the original twin springs in it ! always these were square section but they are not , they are oval unfortunately on is broken so I need to replace it .
I am thinking a 95 spring will do it (or is that too much considering the TP size
also on one the piston head has come off and is at the bottom of the cylinder dont ask how but it still shoots although at very low power ( bounces off a cardboard box ) anyone got one out without damaging it ?
I am thinking 90 Psi air line connected to the end of the barrel see if that moves it ( but open to Ideas )

Any suggestions regarding spring power or seal removal gratefully listened to
