Winter Aircraft Project is this Airfix Bf-109G. It hadn't been particularly well put together by it's previous owner and was missing its propellor. A suitable spinner which more or less fitted was located in my spares box and after the rather pronounced join between the fuselage halves had been sanded down it was glued into place.
This was a kit I built at least twice in the '70s - I remember it was originally moulded in pale blue plastic. One of them came as part of a 'Dogfight Double' set, paired with a Beaufighter.
