No the helmet is not ok!!
Eagle and baseplate and helmet not always together ... Reason:
Base plate of the eagle Screw thread in the middle newly soldered!
No idea what these gray washers with copper do on the base plate of the eagle. Looks like riveted ...
Either the eagle was bolted to the body with the screws which are now verniete which is usually the case with property pieces or with wing nut in the middle with chamber pieces.
Here we have closed hump bolts and newly soldered thread for thumbscrew!
good example no Bugelschrauben only wing nut in the middle

Also, as it looks like if something is restored, the red shade is still there ...
