Thank you indeed for all your replies, as ever well worth the read, however I do feel that £1.00m seems an awful lot of bread for a well used although still youngish Squirril,
Droopy , I have in the past contacted the ASU at Warton, but seemed to get the "Thanks, but no thanks" sort of reply from them in responce to my questions,... but Merseyside are a much friendlier crew and invited me to visit which I did, along with the West Midlands ASU ( who also have some nice Tie tacks), I live in hope of a vistit to Warton, but despite several phone calls over the past 2 years I am still waiting for any sort of a reply!!
They probably dont like amateur flyers.
