Hmm..

Is there a difference between "not up to military standards" and "drill purpose only/not for live fire"?

Wouldn't there be markings on the rifle denoting that it was DP?

If the rifle is DP or not safe for live fire, then was somebody trying to hide that fact by removing the yellow paint? Does not look recent nor did they do a good job.

I'll be bummed if the rifle is unsafe for shooting...
