Helmets without browguard (Stirnbügel)

[M. CVRIVS ALEXANDER]

Thank you all for your input. No rivet holes can be seen on the helmet as it is now, hence my original question. They could have been there when the 1911 article was published. Hoffiller (the author) speaks generally of the traces of the browguard. He does not mention the rivets specifically, and it is difficult to discern them for certain on the photo. The following publications speak both of the traces of the browguard and the rivets, although it is not known whether their authors had the opportunity to verify that info. Anyway, the consensus seems to be that the helmet did have the browguard :wink:
