Hello everyone , took me a while to post again.

Here's Schlueter swivel bail helmet which is named and has the soldier's serial number.
Through Nara I got some information like enlistment date , occupation etc...

You can see on the inside shell the words BP808 are overpainted in light khaki and then he put his name over it. Any idea what BP808 could mean ?

This helmet is still in very good condition.
