NO. The numbers 675 to 699 were never allocated.hesham said:698 was Viking aircraft,but what variant and may be it was a project.
NO. The numbers 902-949 were never allocated.hesham said:935 Merchantman was converted from Vanguard,absolutely a project.
From 'Vickers Aircraft since 1908' by CF Andrews and EB Morgan, Putnam 1995Stargazer2006 said:Allow me to share with you a list of the designations (either Supermarine of Vickers) that are still missing. Whenever you find the time it would be cool to look them up for us...
- 201, 211, 243, 247, 254, 265, 275
- 404, 425, 444, 475

Amazing! Do you realize that this list contains no less than FOUR designations that were previously unaccounted for?Schneiderman said:Some Vickers blueprints were recently offered on ebay. The images provided the following Type numbers and descriptions:
61 Vulcan (Rolls-Royce Eagle VIII) 1922
80 Single Seater Patrol Aeroplane (Wolseley Viper engine) 1923
110 Two Seater Army Co-operation Aircraft DofR 20/24 (Jupiter IV engine) 1925
Vendace General Purpose Landplane with Nimbus Engine 1927?
118 Valparaiso two seat (Jupiter engine) 1926
123 Single Seater Fighter (Hispano Suiza engines) 1926
153 General Purpose Bombing and Torpedo-Carrying Monoplane (AM spec G.4/31) 1931
Viastra Passenger Aircraft (2 x Jupiter XIF) 1930
168 Valparaiso single seat (Jupiter engine) 1929
Only normal since the Supermarine types were included in the Vickers-Supermarine sequence starting at Type 178.Schneiderman said:As you can see the drawing dates do not always follow the Type number sequence and some Types include more than one aircraft design. Supermarine did much the same with Type 178 which includes preliminary designs for at least 12 different aircraft
Indeed. But then at least all these projects had something in common, they were all for a new passenger transport. This wasn't always the case for the other multiple-project designations we found previously!Schneiderman said:So, once again, we have a Vickers Type that includes a number of quite different designs.
Great info. I agree with you on this.Schneiderman said:The Vickers Vigilant 8-engined flying boat, cancelled in 1921/22 was probably designated as Type 50.
In Gunston's book of Giant Aircraft one illustration is based on Vickers' drawing number 5089
The model tested in the NPL water tank, reported in R&M 785, was designated Model 506
So based on what we know about later Vickers project & drawing numbering systems that convinces me that this aircraft was Type 50
Are we talking of blueprints only, here? Perhaps it helps more than you think. You'd have to properly search the documents to be sure:Schneiderman said:A quick check of the RAF Museum catalogue does not help. The Vimy MkII/FB27a has one drawing listed as 3287S, some commencing 32, 33 and 92, and then a large number commencing with letters, A through to W.
Thanks a lot for your pains! I guess we're on the safer side to assume that whatever numbers were allocated in the early stages of the company, a new system started at number #50...Schneiderman said:OK, not much clarity I'm afraid
Vimy drawings commencing with a letter date from the 1960s, drawn by BAC Hurn. There are no references on them to earlier drawings so I wonder if these were 'reverse engineered' from the Vimy in the Science Museum in order to build the replica.
Drawings of the Vimy FB27a dated between 1918 and 1925 have four-figure drawing numbers commencing with 32, 33 and 34.
33xx seem to be the earliest and 32xx the latest, but that may just be a sampling issue, I did not look at many.
The title box and position of the drawing number are not like those with which I am familiar (late 20s/early 30s) so I cannot say if 32-34 are Type numbers, but I do doubt it.
