Here's the run through for Barker. The parts go together in a very straightforward way, and the only tricky thing is deciding which weapon to give him. We only have one studio version painted, so I have inserted a pin for the Plasma thrower (it's a tight fit in the hole so stays on okay), and if I want to use the Fusion lance I pop a little piece of blu-tac in the join - it's worked fine in games so far. People have suggested using magnets to attach the weapons, and that sounds like a great idea - I must give it a try.
Here are the parts in the bag -

That's it for the figures that come in Bag 1.
