I have now a complete list of De Havilland designs from the Airco D.H.1 to the Hawker Siddeley H.S.147, except for two numbers:
  • D.H.13 (which was apparently skipped by the company)
  • D.H.138 (or maybe H.S.138) (which I have not managed to identify)
Any help on the latter would be MUCH appreciated!

Hi Stargazer,


after De Havilland absorbed by Hawker Siddeley group,the designation
D.H. was given instead off it,the H.S. designation.

I know that, but some projects were started under D.H. and therefore can be found under both names, such as the 121, 125, 136 and 146...

Hi Stargazer,


the DH-130 was the last De Havilland design,and for the DH-136 and DH-146,we
can say,formally we can say DH-136,but the official design is HS.136,that is for
example.

I have DH-122 as a competitor of the VC-10 and DH-123 as a twin engine high wing passenger aircraft, not unlike the Fokker F-27, that was abandoned in favour of the Avro 748.
I know Hesham says 're-allocated' in both instances but where does this information come from. How reliable is that reference source?

As far as the Jet Craft MJ-II (note the Roman numerals) is concerned, I found the following in Flight International 29 May 1969, page 892, reporting on the 1969 Paris Air Show: "Jet Craft Ltd Las Vegas (US 25, S) The stand displays models of the 17-seater twin GE CJ-610-6 MJ-III Mystery Jet commuter and corporate aircraft and Six-Seater R-R Viper 522-powered MJ-II jet—de Havilland Vampire T.55 derivatives. Jet Craft's MJ-T1 two-seater trainer (a Goblinpowered modification of the Vampire T.11 by Marshall of Cambridge (Engineering) is shown in the aircraft park and will be demonstrated." The page also has a picture of the mock-up of the MJ-III but I cannot duplicate that. Maybe somebody got better software.

I'm quite we have a topic on the Jet-Craft series somewhere but I can't find it using "Jet-Craft" in the search engine! I prefer not to post pics here (including the MJ-III mockup) because it would be off-topic... If someone could kindly point to the dedicated thread where the Jet-Craft series is discussed, we could have a link to it from here. Thanks.

Perhaps we should rename it to "Jet-Craft Projects" or something like that.
Perhaps not, since the topic also mentions another bizjet derivative that had nothing to do with Jet-Craft.

A middle solution could be to rename it "Jet-Craft and other DH Vampire executive jet projects"...

done this way

Here is a DH document from my past (1958/9) that I have not seen posted. It covers many DH types up to DH 113.
