VP-LAA delivered to Liat in 1969

VP-LIK delivered in 1965, but seems to have had a number of alterations in livery

and 8R-GEU, one of 2 LFDs flown by Guyana Airways.

The only Caribbean operator for which I can find nothing is Jamaica Air Services, who flew sn1593 as 6J-JFJ in '69/69. I'd love to complete the set with a repaint for JAS, does anyone out there have any more details?
Cheers
