The problem with the Walther is it uses a different piston head arrangement. While a whole raft of piston heads can be spun up and fitted to the screw on piston face (as with so many designs) of the Lucznik, the Walther has a one off method of fitting with a keyhole head unit comprising of a leather piston washer and steel keyhole/guide locator. Its a nice idea and dispenses with the need for screws but does cause real problems if wanting to fit your homemade Teflon/leather washer.
I will look at perhaps using this P18 Konceptus mainspring. It fits the piston of the Walther perfectly, then may turn up a guide rod to slip over the existing guide off the base of the grip cap.
The Walthers upper keyhole locater/tiny guide rod at the other end rules out the piston weight fitting in the kit which gave the Lucznik 25fps during my tests. A good 50 fps came from the spring and guide though, meaning one should be able to get the Walther to within 25fps of the Lucznik.
Even more interesting, because as much as I like the LP53 it is a bit gutless power-wise and if the power can be upped smoothly and any mod reversable I am all ears.

If only there was a way of getting the LP3 to perform a bit better eh?!
