I may be wrong but, I'm not liking the shape of the pin.
Searching for anything relating to, Anton Boos, 934 Stamm. Kp. Pz. Erz. Abt. 7, 3 Kompanie, Panzer-Regiment 2, 16th Panzer-Division (My father)
Iím also somewhat concerned about this cross. Rettenmaier used quite a lot of different pin setups on their EK1, but this flute-pin setup looks different from what I have seen before. The L59 mark is also suspicious.
The guy selling it wants $165.00 usd dollars but im not sure if its original the marking dont look right to me
A known fake, run away.
