Which Bablefish assures me is leather-grease...I'm guessing some kind of neutral feed/water-proofer for leather like dubbin? Found (re-found!) whilst preparing an article on the cereal premium kits...
...this red four-engined 'plane - a windowed airliner - probably dates from the 1950's and was given away as a premium with
Solitär lederfett. The company is still going, but the name has been Anglicised to
Solitaire (for a wider market?). The white wheels point to early
Manurba, but it could just as easily be a
Siku moulding or any one of a half-dozen others and I don't know which, yet.
The red
Solitär model is all hard polystyrene with a casually applied sticker, the yellow one is all soft polyethylene and probably appeared as a more generic 'freebie' in 'lucky' bags of sweets and novelties in the 1970's.
