Beautifully done, really stunning.
The wood looks incredible, and you've managed to get the rigging absolutely spot on. Many a time misaligned turnbuckles spoil an otherwise great build, but yours look perfectly in line.
It's good that the engine is so exposed, because it shows off the work you've put in to improve it. And that exhaust looks metal - is it a Rexx exhaust, or have you transformed the plastic part?
The gun looks very good. If I was being very, very picky indeed, I would perhaps look to differentiate the bullet feed, where the bullets and the fabric could maybe do with a little paint work to seperate them a little more? Not that there's anything wrong with how it looks at all, I just can't find anything else in the build that's not utterly perfect!
Thanks for sharing, I look forward to your next build, I love learning from builders on here, just so much skill on show.
