EK2 Iron Cross / Eisernes Kreuz Wächtler & Lange With LDO Numbers L55 in 100% mint condition

I have this item on “commission” sale, I just trying to help the owner sell.(I did not set the price)
Part of a larger collection, presumably, other rare pieces will become available in the later time.

EK2 Wächtler & Lange with marked mark LDO number L55 on the frame on the back side

The condition is 100% in mint and perfect piece, and the marked mark full, total and nice, but as you can see in the picture, the light of the flash is very reflected from the frame, so the marking is not really visible
the last picture was therefore taken without flash
