Hello,
This single photo, of mediocre quality, shows that:
This should be an M60, but :
---The eagle is too big, it should be flush with the top edge of the visor, but here it clearly encroaches on it.
---The visor should be angular. Here it's rounded.
---The tip is not correct, and should have a simple Perlring troop. The cruciform base is not correct, there should be no border, for a troop helmet.
Even the Mappa's Swedish Pickelhaube M/1845 shows a compliant tip!
Other views should enable us to detect other anomalies.
