Hi Phil - I read your post above with interest about a Jab engine being stolen from a UK airfield. I saw this ad on craiglist just the other day for a new 3300 engine and thought it was a bit weird. After just reading your post I thought maybe it could be the stolen engine you mentioned in your post. I have sent you the link. Maybe it is worth having a look in to to see if they can be caught. Just seems a bit too coincidental and seems to add up.
