Notes
- This was a series of aircraft used in the integration of various radial engines into the Type 504 airframe
in place of the rotary, along with the development of an entirely new undercarriage that came to symbolize the Type 504N.
Non of these can be considered a fully developed Type N.
- Jackson [1] defines these four aircraft as
an advanced interim type with oleo sprung skid-type under carriage, but photograhic evidence [13] shows at least G-EBHC, which
lasted only a month before crashing, was a fully developed 504N.
- Fitted with a 200 h.p. Wright J-4
powerplant. The one aircraft built was initially a single float seaplane, later converted to a landplane with Wright J-5.
RCAF designations were Avro Wright Seaplane (A.W.S.) & Avro Wright Landplane (A.W.L.). A further six were to have been
ordered in 1925, two seaplanes and one land plane, but the order was never placed.
- Fitted with 180
h.p. Armstrong Siddeley Lynx IVC powerplant. First three were built as seaplanes, using the same single float design as the
Type 552A, were delivered in January 1928, this being followed by nine landplanes delivered in February 1928. The floatplane
version was designated Avro 504NS in the RCAF.
- G-ACZC, registered October 1934, was possibly a rebuild
of G-ACRS, which crashed 6/34. both are shown with the same military serial.
- G-ADEV impressed as BK892
under file contract SB.7560/E1. To Instructional Airframe 3118M then the Shuttleworth Collection as G-ACNB in October 1981
and reconverted to Type 504K. Registration restored to G-ADEV in April 1984 but carries military serial E3404.
- G-ABVC given in G-INFO as ex F8841, but this was 504K supplied to Argentina. Jackson [1] and LAAS [9] indicates ex F8834,
which would make it a 504K converted to a 504N. Vic Smiths Accident report [10] also shows as 504N.
-
Known locally as Avro 504K Lucifer, these were very similar to the developmental airframe G-EBFB.
- Note
that the Avro 504K displayed in the Canadian Aviation and Space Museum as “G-CYFG” is not in fact that aircraft,
but its provenance is worth recording. The following from the CASM website [20]:
"Manufactured by Avro in England
1918 (Mfr. No. A958), RAF registration H2453; Frank F. Valcourt, Pawtucket, Rhode Island, U.S. civil registration #5918, fitted
with LeRhone engine 1928; Rooseveldt Field Museum, early 1930’s; J.H.C. Palen, Rhinebeck, N.Y., U.S. civil
registration N8736R 1951 (used for flying displays U.S. and Canada); Purchased by RCAF, delivered Trenton, 19 May, 1966; Rebuilt 6 RD Trenton (Crew Chief MWO H. Tate) 1966-1967, TOS 1 June 1966; Assembled Rockcliffe, Clerget engine from
National Research Council of Canada (NRCC) installed 12 Dec., 1967; Now on display at CASM, equipped with Turnbull Variable-pitch
Propeller. Note: 504K, RAF registration H9555, originally assigned Canadian registration “G-CYFG,” TOS May
1924, converted to 504N 24 July 1927, SOS 30 May 1930." How H2453 came to be in the US originally is unclear. - Alberto Fernandez Donoso and Ray Sturtivant [6]: "Avro supplied six 504-Os (C/n 355 to 360) to the
Chilean Navy, these being modified versions of the 504N, given the Chilean serial numbers 82 to 87 inclusive and probably
assembled in Chile." The same reference has a photograph of an Avro 504O '19' of the Chilean Navy converted to a landplane.
The article then summarises as follows: 1929 6 Avro 504-O 82 to 87 (c/n's 355 to 360). seaplanes for Navy, deld 8.29.
One later as landplane "19".
Dan Hagedorn [7]: "Regarding the alleged Chilean Navy Avro 504Os
delivered in August 1929, I must confess to being puzzled by the "high" serials quoted (e.g. 82 to 87). Try as I
may, I cannot come up with any reason why the Navy should have had serials such as these at that particular date. The photo
accompanying this statement, on page 7, of Chilean Navy 504O serial "19" further confuses me! I must agree, however,
that 19 seems a much more reasonable serial number for a Navy aircraft at that date."
George A. Jenks [7]:
"There appears to be confusion about the Avro 504Os: Avro supplied seven a/c in early 1927, serialled 15 to 21 inclusive.
These were all tested with wheels at Woodford (whence the photo of No. 19) before going to Hamble for the fitment of floats
prior to delivery. These machines probably bore constructors numbers in the range R3/AV/- for which no complete listing seems
to have survived. They were probably supplied with both sets of undercarriages, as Jane's 1927 quoted the Chilean Navy as
using "Avro lynx land or sea machines". A further batch of six aircraft were supplied in 1929 bearing the c/ns 355
to 360 and serialled 82 to 87 respectively. However, the first serial number conflicts with the last 504K..."
Dan Hagedorn [8]: "Four 504Ns, frequently cited as going to the military circa 1925 (E444, H2512, H2562 and F8841),
seem more likely to have been sold to civilian users, as no evidence has emerged to support EMA or Aviacion Militar use.
Finally, Insignia magazine [11] adds further twists: "Five Avro 504Os were later constructed at the El
Bosque factory from spare parts (these machines wore serials in the range 20 to 24)." An accompanying photograph positively
identifies serial 82 as a Type 504K. - Export Type 504Ns and 504Os were either supplied in mixed batches or as 504Ns with optional floats,
hence for this site this author will use the term Type 504N/O.
