Hi Tony et al
The pictures are very good.I saw the Magister about a month ago.It would serve it's preservation if it were raised on axle stands and had it's tyres pumped up, as well as having the cockpits covered over.The wings should be stored in canvas cradles and not allowed to rest on the concrete.The wing interiors should be covered off. All exposed metal components should be lightly oiled or greased.The prop should be given a wipe of a lightly-oiled cloth.All bird and insect-related debris should be wiped off.
