Stroke lengths, TP sizes and SCR for various springers...

Fair point but if custom builds are added you will need this info. Also, as in the TX, different weighted pistons by use of different top hats dictate calibre size in std form. Don't know how much detail you want but suspect more rather than less��
Anyway, here's some data on a TXHC

Stroke - ~98mm
TP - ~3.65mm x 9.8mm long
Piston wt - ~225g (.177 add 27g for top hat)
(.22 add 16g for top hat)
Bore dia - 25mm

Hiya

Can you just confirm if thats a MK3 and standard? Have added details above

Many thanks!

Yes, Mk3 Std. The Prosport is basically same spec if you want to add this too. Not sure about the very early ones though.
