Tritar500, only freighter aware of is Thai Sky International -10. Its been standing now for about one year and like most requires some urgent AD upgrades and importantly engine turbine shaft inspections.
The company however is very indecisive about their and aircraft's future one minute wanting lease other to sell - but at unrealistic price.
You can see more about aircraft s/n 193C-1097 on Thai Sky website
www.thaiskyairlines.com/main.html or obviously on airliners.net or on the flytristar web pages.
This -10 freighter was flown by now (2006) late Captain Ken Conde and as rumour goes quite a few are interested to lease or buy but concerned about period now on ground and future of such older machine. This was allegedly only dedicated freighter ever manufactured in Lockheed factory before production was halted. (stand 2 be corrected).
