So I decided to have a go at rotating the cockpit on my B-Wing yesterday
Turned out to be an arduous process of carefully sawing off the front with a craft knife.
Unfortunately I managed to break the Right / Bottom gun:
This forced me to take to my bits box for some replacements (I lost the part completely somehow)
I found some WHFB dwarf handguns to use (obviously I didn't want my guns being different) and here's how they came out.
Obviously I wish I hadn't broken it but I'm OK with the bodge fix I guess.
Moral of the story for me is "don't try and do any conversions!"
