Well, I've given up on any type of 727-200 in my price range. I found one in the states, but they don't ship to NZ (Might be a way around that). But thanks to Mark and iwik for the input.
I have managed to find an old Airfix 737-200 (ANZ/Ansett) version, and thanks to " Oldmodels decals"...
https://www.oldmodelsdecals.com/ I have, and will be getting some decal sheets to replicate dear old ZK-NQC in one of her many guises before leaving NZ.
I'm now looking for aftermarket replacement JT-8D engines with the hush kits ...maybe at
https://www.authentic-airliners.de.
Really starting to wonder what the hell I've got myself into ...but it's fun. Should be in lockdown here again within the week, so I will need something to do.
Re the shipping to NZ thing, I recall a few years ago when I was collecting replica watches, NZ POST has a thing that gives you a US postal address, which is run by NZ Post ...they receive it, do the customs thing and send it home to NZ.
The savings are negligible, but it gets around those that won't ship down here....not sure if it's still available.
