OK - That one is throwing me for a loop a bit...I'm used to pre-60's bottles, but this is alot newer: Made at least after 1977 (Barcoded).
The Old Parr is mostly popular in Japan & South America, and is not even marked in most countries...I do see that your bottle was sold through a Hong Kong Duty free shop (HKDNP - Hong Kong Duty Not Paid), but honestly that is
about all I can tell you on this bottle.
It currently sells for $65-$100 bottle, depending on where you find it.
Have you tried Diageo (They produce the Old Parr brand line) ?!?

Sorry I couldn't be of more help on this one....
