Blimey, Ewan, you're a star. That's what my original notation says, it is Biggin, and I believe the year is '74. Last time I googled on this aircraft, couldn't find out much about it. Any pointers ?

nine made, 220hp Franklin engine, +8 - 8g. Acrostar came together in 1969 from a Swiss design by Arnold Wagner. The Swiss wouldn't certify it so Wagner took it to Germany. Wagner sold his KZ-8 to pay for the new aircraft. First flight was April 16 1970. Wing was symmetrical, had do incidence or dihedral and the all moving elevator was linked to the flaps, which in turn were linked to the ailerons. The Acrostar promptly took the Swiss Aerobatic Championships in 1970. It was flown by Wagner and Josef Hoessl and won first and second place. It was then flown to Hullavington for the World Championships, coming in fourth. Wagner then retired from aerobatics and became completely involved in certifying the aeroplane. The fuel crisis in 1974 and failure of Franklin engine company halted plans for a Mk3 version.
In 1971 the Swiss national aerobatic team was founded and selected the Acrostar to be flown by architect Eric Muller. Muller invented the 'Spiralling Tower' manoeuvre with his Acrostar in '74. Christian Schweizer came to the fore using this aircraft and went on to win many Swiss and European competitions. Schweizer considered it one of the best aerobatic aircraft he had ever flown.

There's a nice set of plans in the Aeromodeller range.

Dragged this pic from an old album the other day and scanned. I'd written on the back which aircraft I thought it was, although I'm not totally sure. Any ideas, also location and date (I'm a bit more certain of those).
