Bugger, it must have been a Revel 'coz I ain't never heard of Renwal !!
As you say, stuff is disappearing out of the noggin !
When I was REALLY young a mate had a Frog 'plane, all shiny, real aluminium, could it have been a Mustang (P-51) ???...help?
I've still got the tug that my dad built for me out of Model Maker plans, the ones that were included, not ordered.
