I've never worked on (or owned) the 52, J, but most of those quality 25mm set-ups run fine at circa 80mm stroke, so I think that's where I'd be aiming.
Got the Cindy's Shooting Shop stock reoiled tastefully (not real shiney just s sheen) bow I'm undecided on the power plant ......it's .177 running a 25mm reduced cylinder but I need to settle on stroke length tx200 piston with an extension plus longer rod gets 80mm standard lgv piston gets me 100mm soooo I've just ordered a 10mm extra extended seal (customseals) .
Any thoughts are welcome thanks in advance Jonathan
them there springer's are soooooo addictive

80mm will be fine on the diana, as it has such a short port, so it's very efficient. 85 is the max I'd consider

Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
