With all of your help above I think I've now sussed it!
I believe that it was a combination of factors at play here. The housing (607V2 in the parts diagram in my first post) was sitting too low which I believe was causing the lead screw to bind. I think this could still do with some adjustment as it doesn't appear to be able to move up enough. Alternatively a spacer under the lead screw nut may have a similar effect.
In addition to the above I also loosened off the gib a touch and now the handwheel turns freely and smoothly (possibly a little too freely - I keep overshooting the mark on the DRO!). Still not sure what the rubbing noise is that I'm getting - I think I will save that investigation for another day but for now the lathe is a pleasure to use again! It was becoming a real pain - especially when i am parting because it reduced the feel through the handwheel so I was less able to guage the pressure on the cutting tip (1mm carbide cutting tips break very easily if you're not careful!).
Once again thank you to everyone above for your suggestions - If it wasn't for the words of wisdom I'd probably be posting a thread in the shop blunders section on how not to machine the housing!
