Hi Ed,
No problem at all, thanks for getting back to me. Steps 1 and 3 are virtually identical to the Airfix/Academy kit that I have. Step 8 differs in the detail for attaching K34 and J12 to the underside of the fuselage. Your instructions clearly do not show any indication of the ability to rotate the turret while mine clearly do, yet the component pieces are identical. If my instructions did not have the 'no cement' squares I would have happily cemented the chin turret in place (which is what I will do now).
Interestingly I have contacted the Airfix/Hornby Customer Care centre via e-mail. They have allocated me a report number but otherwise have ignored my request for help. Even an 'Oops, sorry, our mistake' e-mail would be better than stoney silence.
Anyway, thanks again for all your help, I hope your special project went well.
Rob.
