I did one of these the other day. The strip down is the same as the Diana 22/23 near enough. On the one I did, there was an extra bobbin between the guide and the sleeve that holds the mainspring in and the piston rod seems odd (problem mentioned in my post of 4/11/2010). You cannot be sure with some of the later Milbro stuff. They did seem to go very British Lelandy in the 70,s and I would say that unless you are a collector, you are better off with an earlier 22/23 or Webley Jaguar/Junior/Ranger. Sorry this is not detailed but its easier for me if you look up the 22 strip than me typing out a full strip down.
