Hi
This is the last version of the Bavarian Pickelhaube, around 1914 (wappen without leaves).
Although it is not my period, it looks like an honest OFF pickelhaube to me.
The Wappen has its 3 crowns voided, which is good. The spike is tall (extra spike)
The "Vergoldung" is very dirty and has became almost red.
Best regards
Eric
