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

This may not be appropriate within this 'Designation' section (Mods please feel free to delete).

I was looking around for a listing of British Dec 1923-Jan 1948 B Class registration number and couldn't find one - many such numbers are available online but not pulled together into a list. So, I have compiled such a list for de Havilland (which was assigned the 'B' class letter 'E').

Here's the problem. How B Class numbers were to be assigned was left up to each company. De Havilland simply 'recycled' their registration numbers as airframes gained full civil registration, military serials, were written off, etc. So, finding an example B Class registration number is hard. But how to determine if you've got them all?

A note on style. In most cases, de Havilland B Class registrations were painted on airframes as 'E.1.', etc., a full-stop between the 'E' and number and after the numeral. The only exception I've seen is 'E.8' on a D.H.94 Moth Minor.

Related is another series of larger numbers. Examples found are E-0222, E-0226, E-0232, E-0234, and E-0235. Does anyone know why there were two series of 'E' numbers? Or can anyone add to the 'E' numbers list below? (I am especially curious about the 'missing' E.15.)

De Havilland Aircraft B Class Registration Numbers

E.1. = D.H.80 Puss Moth prototype (later G-AAHZ)

I haven't got a copy yet so can't tell you if it has all of DH's E. numbers, but I'm sure it will have a comprehensive listing.

Cheers Hood! So, this work has already been tackled ... and comprehensively too from the look.

A lovely summary of what 'B' reg are/were in your link too:

"B-Conditions identity markings have been applied to British aircraft used for experimental purposes and flight testing since their introduction in 1929. They are neither a civil registration nor a military serial number. They provide an identity to aircraft which do not yet have a Certificate of Airworthiness and are used prior to being placed on the civil or military aircraft register."
