Thanks for the link, I’ve already seen and read that but as you say it dosnt cover a complete total re build. I came by the pistol in Kidderminster when I bought a steam engine of a chap on gumtree and he had various air pistols his deceased father had in his garage. Two were illegal brococks (bacs system) and the cp88 completely dismantled in a lovely oak canteen of cutlery box together with a complete smith and Wesson 586 which was cocked and fired etc but a bit stiff. I paid £50 for the two co2 pistols hence I don’t mind paying someone a reasonable amount to re assemble the cp88
