Royal Jamaican Rum Aged 12 Years. This is a rum brand from National Rums of Jamaica (NRJ) and hails from the Monymusk distillery. I have seen this brand online but have rarely seen any reviews or discussion around it.
Monymusk does rather fly under the radar a bit, when it comes to online rum discussions etc. Appleton, Hampden and Worthy Park get much more coverage when it comes to Jamaican Rum. The only review I could find on this brand from any serious writer was a 20011 review of their Gold entry level rum by Lance over at The Lone Caner.
