Thanks for that Damo......yeah, I knew she was comming. She is just a re-pop of the old Airfix 1:144 707-400 with the Rolls Royce Conway donks but it's not a bad kit for it's age.
For better technical accuracy in a 1:144 Boeing 707-400 you would be better off going for the Minicraft kit, and if you wanted a good 1:144 representation of a Boeing 707-300 you can't go past the superb Authentic Airliners kit or the Welsh kit as a close second.
The recently released Roden 1:144 Boeing 720/720B, (smaller brother of the 707 family), is also supposed to be pretty good and could be used as an effective base kit for building the unique short-body Qantas Boeing 707-138/138B
