This pickelhaube is going to be auctioned at an estate sale in my area and I have been unable to identify the front plate. From the issue stamp it appears to be an Armee-Korps (Coblenz) but the front plate is not familiar to me. I know the photo's suck but they came from the auctions website. I am wondering if it would be worth my time to attend this sale or is this a fantasy item. Any help would be greatly appreciated!
