After some excellent replies to a previous identification issue, I thought this would be the right place for this item.
I was told the blade is from a 109 recovered from Germany (I know...buy the item not the story) but the style and materiel seem very similar to my other German blade. It measures 140cm long and 30cm at its widest (although it may have originally been wider before the damage to one side). One of the pictures below shows the stamping on the base, I assume the 'hge' is the manufacturing code but any insight as to the meaning of the markings would be greatly appreciated.
If you are interested, the 9-12087.10 was fitted to the Bf109G versions with standard DB605A engines. The DB605 powered Bf109 aircraft with GM1, AS or D engined or with MW50 were generally designed to have the 9-12159.10 blades.
Cheers
