ANNNNNNND Alex (from "The Land Of Oz/Aus" .... otherwise known as "The Lucky Country" or "The Land Down Under") wins
QTV STAGE III Hush Kits it "IS".
None of the smaller DC-8-50's were ever re-engined with CFM-56 turbofans.
Less than a handful of DC-8 SUPER 62's were either.
Although economy and range of the few upgraded -62's was greatly enhanced once modified their lower payload capabilities made them (and the -50's too) less attractive candidates for CFM-56 turbofan conversion.
The cost of the re-enginning program was high/prohibitively expensive for operators other than the larger/major carriers still flying DC-8's during this period.
Smaller air freight operators in particular still found themselves obliged to make their aircraft "noise compliant" though .... or .... be banned from operating into the like of US territories within which noise noise regulations were mandatory.
Some 110 DC-8 SUPER 61, SUPER 62, and SUPER 63 aircraft were upgraded to DC-8 SUPER 71, -72, and -73 specification as a result of the CFM-56 turbofan re-enginning program of the 1980's.
More aircraft might have been converted had cheaper Hush-Kit and Quiet Nacelle modifications not become available as promptly as was the case and had the implementation of Stage 2 noise regulations not been extended until January 1st 2000.
A number of DC-8-50, SUPER 61, -62, and -63 aircraft were instead modified with cheaper and almost equally effective forms of Hush Kits and Quiet Nacelle treatments .... among which the QTV STAGE III modification was just one, among a number, of cheaper options available to make DC-8-50, SUPER 61, SUPER 62, and SUPER 63 aircraft Stage 2 and stage 3 noise compliant.
The particular HK's featured on these modes are the QTV type which were fitted to FINE AIR's DC-8-50F and SUPER 62F fleet.
Alex .... you can pick up your prize (a small, but "FREE", packet of peanuts .... your prize for "observance and accurate guessing") from HJG reception in either NZ, Canada, or Colombia. You'll need to pay your own return air fare though in order to be able to do so
