Thanks for the response, yes I am looking for 1:200 scale. Looking at the database both of your 1:400 models look amazing, you are very lucky to have them and if you are selling them I wish you good luck.
I have 2 of the Gemini Qantas F1 models (2172) and a Golden Wings example (3762).
Gemini price is US$60 and Golden Wings US$40 plus shipping which would be US$18.
Give me a shout if you're interested in either.
