Man, thats no good, you really have to be careful, the halves can only be seperated enough to work on, any more and you could strain the wires or break they like you managed - was it a pull accident, or an series of tragic events that unfolded?

Gun mechanism is fairly sturdy IF the rubber bung stays in place. Dunno if your pack of dogs (lol) had dud rubbers or what, but to have to buy 5 thats crazy. What was wrong with the rest of the Bulldog that fired well? I mean why did you swap the turret from the good tank onto another Bulldog??
