I looked into trying to improve the 28 a few years back but came up blank..
The leather washer had been replaced and was well lubed in what smelt like linseed which was probably ideal, while the fits of the piston and guide rod of good quality typical of firearm quality build pistols of this type ....Webley Seniors etc..
The mainspring was also in good shape so I just smoothed out the action and cleaned out any grease, replacing with a drop of pellgun and a slim slip ring over the guide.
At the club I put around 20 clearing shots through it and handed it back to my friend as apart tuned accurized 28 delivering 352 fps avg.
No better ..
I'm pretty sure the barrel is just a tad too short to get any real accuracy going, while the trigger completely detaches from the action for cocking which means it's never going to match say a well lubed Webley trigger
.177 I got 2.5 inch groups and occasional flyers at 10 meters. Which is not quite what I make with a Webley Junior with adjustable rear sight but smooth bore barrel.
Beautiful hefting pistol though....maybe best ever for feel ...
Maybe I'll look at it further ....but at the moment trounced for performance by the HW70 we have....1.2 inch groups off hand and 430 fps
The 70s barrel seems to accept pellets easier and has a lovely trigger and slightly greater size internals
I am going to look at major tuning of both but it needs new components really.
I want to try to exceed 450 fps with the 70 but think this too optimistic and some for the 28
