Correction!

Just referring to my post above, although the high powered Sheridan was, reportedly, the gun involved, I seem to remember that this event was the major catalyst for the introduction of the 12ft.lbs power limit. The gun wasn't banned and we later "enjoyed" the castrated later versions. Maybe a reduction in hammer spring length initially, followed by the relief valve on the pump??

And I'm pretty convinced that the coming of springers capable of the required power, with just one easy cocking stroke, built to a higher level of quality and with better triggers than the American pumpsters, led to dwindling popularity and appeal.

And, as per above, those pesky PCPs.......
