.22 auto nine information

[shoba]

A friend of mine just bought a FTL .22 auto nine pocket pistol.We think its the older version of the Wilkinson Sherry .22 pistol,or visa-versa? We finally figured out how to take it apart,but there is a threaded bushing that threads over the front of the barrel,and it looks like it might of came with a special tool to remove and tighten this bushing.I told my friend not to shoot it until we find out more about this bushing.I've been searching the net for a couple days with no luck.Can anyone here shed some light on this little pistol? It seems to be well made,and we are itching to try it out! THANKS in advance
