Two helmets

[zeebas101]

Hello,
I recently saw these two helmets in an auction and was wondering if they are 100% original or not. The first is an Oldenburg DR19 officer’s pickelhaube, which looks like an earlier model based on the overall height and the style of the one visible nut inside(?). There also seems to be a Prussian NCO cockade on the side along with the Oldenburg officer cockade.
The second one is what appears to be a KR2 officer’s helmet, but overall it just has a suspicious look, even though the parts are technically correct apart from the 2 Prussian cockades, one of which is an enlisted cockade? From what I can see the wappen has a voided crown, making it an officer’s, and the liner looks like an earlier pattern officer liner but the rivets on the neck guard seem to be split pins, which I haven’t seen on the examples I looked at. Also, the silver ring on one of the cockades does not look like an officer’s.
Not sure if I am missing anything on these. Overall the Oldenburg one looks fine to me but the KR2 is suspicious. The auction house is Centurion Auctions.
Thoughts?

I would think that the K R 2 officer helmet would have a different liner ?

Do you think this liner was added in at some point? My first thought was that it was just an older officer liner.

Somehow didn’t notice this yet, but both cockades on the DR19 are incorrect?

Hello,
The 0fficier DR19 is flawless, except for the Reichskokarde, which is an infantry “Portepee” (if it's 51cm in diameter). The officer's Landkokarde may have been repainted, as its mint condition does not match the patina of the helmet.

The KR2 0fficer is also fine, except for the roundels. With its low tip and basane cap, square teeth and double hole for the adjustment lace, it's a cuirassier officer's M67/71 model. The silk liner was only introduced for cavalry officers after 1890.
As this helmet has undergone a number of detail changes, on the M97 it must remain in the M71 configuration, i.e. with a single Prussian officer's cockade on the left side. This single-stripe cockade is acceptable on older officer models, provided it measures 63cm in diameter.

Thank you for the details!
