Cheers mate!
Re the Sunderland, I have two for my RNZAF collection: one will be converted to an MR.5 (Pratt Whitney engines), the other a Mk.III transporter with faired over turrets.
What this means for you is I have a full set of spare turrets, bomb gear, and Mk.III engines and props going, plus a spare canopy if you need one. Also, if one wing is damaged but repairable, I can trade you for one of mine, as I won't be doing these for quite a while yet.
