Hi all and thank you for the replies.... Most probably they had an overhead crane/derrick the type found in naval dockyards. The FW-190 weighed in at 4,300Kgs loaded, so not a heavy-weight by any means. However it might have been a bit of a pain trying to position the FW and the crane in the proper spot not to cause and trouble whilst hoisting the plane. Moment of rotation, causing the crane to topple. Will scout through your links and go from there..
Thanks again and all the best
