O.400 Tyre size, 900×200
Denys and flyernzl
Good spotting, I did not notice the tyre when I was last at Ferrymead.
It is not from a O.400, according to FS20, Schedule of spare parts for Handley-Page Bombing Machine, O.400. This book shows that 4, “Wheels, Palmer (off set—900×200)” are fitted. The illustration given also suggests that the wheels do not have spokes and are in fact solid.

F.S. Publication No. 20., Schedule of Spare Parts FOR HANDLEY-PAGE BOMBING MACHINE O.
For those interested in this subject, the Schedule of Spare Parts of the O.400 is available on line.
It includes all the drawing numbers and illustrations as to what the parts look like.

5C/557 ?
Do you mean 5C/557?
Whirlwind IPB
If you are in or near London you could pop along to the RAF museum and look up the reference numbers for the instruments. They may even send you copies of the relevant pages if you were to ask nicely.

Air Ministry Specification G.392
I find I have this specification in my collection, dated September 1936
Specification for Bombing Teacher Mk III.
Unfortunately it doesn’t include the drawings, thou all the 61 drawings required are listed.
I also have descriptive and instructional notes on the bombing teacher.
It is suggested that these notes are to be used before the information is formally embodied in a printed Air Publication. Since I acquired these documents in Australia, it most likely is referring to an AAP.
These notes include 18 pages without diagrams as to how to install and use
Is there any specific information anyone would like to know?
36U
If the number 36U is a RAF section number then it is off a Cheetah engine.
Thermographs
Lyffe
I have found reference to the type of instrument you are interested in. The following information is from a document dated May 1920.
6A/112 THERMOGRAPHS, 2 hour
6A/113 THERMOGRAPHS, 6 hour
6A/114 THERMOGRAPHS, self recording
Hopefully these are the instruments you are interested in.

This site will give you hours of joy as you search for things, The OCR is not perfect so some things will not be found because of the mis spelling. You just got to be inventive in your searching.
Smiths Advertisements
Mathieu
I can not help you on this one as I do not have any catalogues from this period. I however know where you can see advertisements of Smiths products for the period. If this is of help please reply and I will offer the information.
I however am also interested in this subject as I would like to see what aircraft clock and watch products were on offer during this time.
In my database I have the following entries :
26AD ?
26AH Botha
26AK Henley
26AP ?
26AR Botha? not sure about this one
26AS Mentor and Magister
26B ?
26BH Hudson
26BQ Queen Wasp
26BR ?
26CH ?
26C Ripon
26D Iris
26E Fury
26F Vimy
Please note some of these codes got reused so there could be later aircraft that share the same codes.
The gasket is most likely made in Canada
The gasket is made by Avro Canada based on the NSN code on the packaging. Knowing that the Canadians had different section numbers to the RAF, the airframe code 26CH does not shed any light on the subject.
Cambridge Aero mixture indicator
Rehlombard
It has taken me a while to locate the book that has all the detail you require.
In the book, Pilot’s and Mechanics Aircraft Instrument Manual, by G.C. DeBaud, The Ronald Press Co., New York, 1943, there is 18 pages on the Cambridge Aero Mixture Indicator. It goes into a lot of detail as to how it works, testing and trouble shooting, and how to connect for a variety of aircraft configurations.
The system works on the Wheatstone bridge principle. 2 legs of the bridge have identical platinum coils located in cells, one cell is connected to the exhaust and the other to a known gas located with in the cell.
A little more detail is described in this link.
