Some years ago when I was a Airfix Club member, they had those on special order for members, I bought three of them ---- still waiting to be built and converted to other versions
As an aside, I also bought a second hand one from Rare-Plane Detective, when I got it I found it had an absolute gem of a find in it, an Aeroclub Astazou conversion in it, and not your usual one either which was a white metal prop & engine front, this one had vacuform nacelles too.
