Stoeger / Boito A681 coach gun.

[Smick]

I am trying to find a 'Take Down' guide for the single trigger 20" Stoeger / Boito A681 coach gun which I use for Cowboy Action. I live 'Bush' in Queensland Australia and find it very difficult to find a gunsmith out here. Any help from other members would be a great help.
  I have tried "Radocy" who do a lot of take down guides but not for the above shotguns mentioned in this post                                 
                                                         Thank you in advance, Smick.
