I got a question about the PCP guns ????????

Back in the day in the 70s I was shooting a FWB 124 , I had the Beeman catalog I read from cover to cover,
I also had a couple ood pumpers , Crossman, and maybe a few others ,
We had beer drinking party’s with target shooting on the side, Great fun , great training , and big hangovers, LOL…
Remember the good matches, Yep we lit them up at 20 yards,
So what year did the PCP come to market ? I must have missed it, but I was busy with life….
Life and all got in the way and I fell out of the information on the air guns,,,
Now being retired and the computer age I read up on some of the new guns.
30 something years of adjustments nothing could out shoot my FWB 124, One shot one kill, sparrows were the number one target.
So I popped down a crazy amount of money on a 25 Marauder and a hand pump.
My eyes have seen the light, The rest is history…..
