Indeed it's a shame, but on the other hand this beauty has the biggest ratio of the original parts among the 109's in Europe (about 80%).
I saw the photos of it being picked up from a lake, it had even some original paint on fuselage.
This particular plane belonged to the training unit stationed in the northern part of todays Poland and crashed into the lake during one of the training flights. The 109's pilot, young feldfebel (or oberfanrich - don't remember now) noticed some defect and wanted to make it to base, but unfortunately he just "landed' in the deep of the lake...
In other lakes there have been discovered two Me 210 planes.
