Is it me or the swan neck regulator sitting on the sword thing? Sorry I'm not that technical. There was a 177H for sale just now that looked the same way. I though the sword was to sit above the regulator.
Yeh this is what I thought too, mailed him back as it looks like the swan neck is sat ontop of the regulator. Apart from that, can't see any probs & that'll be an easy fix for him I guess.
