Airfix should do the Commonwealth Aircraft Corporation CA-27 Avon Sabre. The Sabre, while a US design, is an important early jet fighter for the Commonwealth. Not only was it used by a lot of Commonwealth air forces, including its three oldest, Sabres were produced in two Commonwealth countries - Canada and Australia. The modelling community is very well served with J47-, and Orenda-powered Sabres. What it lacks is readily available Australian CAC Avon Sabres. For general information on the Avon Sabre, see here: http://www.adf-serials.com.au/2a94intro.htm, To date, there are three conversion kits, 2 in 1/72, and 1 in 1/48. The conversion from North American/Canadair Sabre to CAC Sabre entails a substitute fuselage. The conversion kits available are designed for the Fujimi/Italeri/Academy/et al kits. I think Airfix could, without inordinate difficulty, do a 1/72 Avon Sabre based on its 2010 Sabre. If you look at the sprues, both sides of the fuselage are on a single sprue, and the only thing thing to change is the fuselage, and the addition of Sidewinders. In 1/48, more reworking would be necessary, but I'd like to think it was feasible.
