ERA P14 Brass plate

[LawrenceN]

Greetings fellow gunnies! I've recently come into possession of an ERA P14. Mostly, it's pretty run-of-the-mill. As per usual, the volley sight disc is still on the forestock, but the pointer and the folding peep are absent. From what I can tell, it's not seen a lot of use and under the stock there's still a lot of old cosmoline. The bore has lots of rifling and no major pitting. My question to you all is a translation of the brass plate overlying the brass unit disc. My research hasn't turned up any definitive information so I'm asking the pros. Anyone familiar with these? I was told it was Indonesian, but that doesn't seem to make sense to me. Any solid intel would be most appreciated. Thanks in advance.

One of many Dutch issue P14 left in Indonesia or part of large lot bought from India and then used by the Indonesian Air force with brass rack number plate, I have had 2 of these rifles, the Indo air force kept them until the 1980's when they then sold them off.

SAU means in Indonesian Senapan Angkatan Udara (Rifle for Airforce) I still don't know what CIE means. They always work with abbreviations.

Hey JP! Not that I doubted you, but it never hurts to get a second opinion. Thanks to mkrnel, I know what the SAU means, but I still don't know what the CIE and HSN stand for.
