DC10-30 and 40, the JT9D powered 40 was sold only to NWA and JAL, it was thought that the 40 series would attract operators of 747 with JT9D, so there would be common engines... but the 40 was not a good seller... even on the used airplane market, the 40 series are difficult to sell, operators buying old DC10s prefer the models equipped with CF6s...
Interesting to note that Boeing produced the 747-245F (For Seaboard World) with JT9D-70s and special nacelles which were to be common to DC10s... these nacelles ended up as maintenance nightmare (reversers)...
To end the subject of the DC10, be aware that Douglas also tried to market a DC10-20, which was to be a DC10-10 also equipped with JT9Ds... but nobody ever ordered these...

It is my understanding that the DC-10-40 was originally called the DC10-20 but that Northwest didn't want the perception of it being "less" than a DC10-30, so for marketing purposes, the JT9 aircraft was changed to a DC10-40.

The only other version was the DC-10-15. It was specially made for Mexicana and Aeromexico for operations out of the high altitude (and hot temps) of Mexico City. It combined the Fuselage and engines of the -30 (more fuel capacity in the center tanks and more power from the engines) with the shorter wing of the -10. Only seven were made. According to the JetPhotos site, the last operators of the planes were Sun Country with four (all either stored or broken up), Aerowings with one (stored), and Electra Aviation with two (still flying).

One smooth landing is skill. Two in a row is luck. Three in a row and someone is lying.

Far to be a knowledgeable DC10 person, the 30 and 40 series were absolutely similar in airframe, except engines (CF6 versus JT9) - dimensions were the same... I understand the 15 series had some features of the 30 series (i.e. power of higher CF6 dash numbers) to be able to operate from MEX...
