This is so helpful, thank you for this information and help with solving this photo mystery.

I believe this instrument is something to do with military, probably naval possibly 1st - second world war. It says W Ottway and co (based in Ealing) on flange..... has anyone got any idea what this is?

Yup, that fits.   He will be the seated figure.

Writers were the ships administrators - responsible for pay, correspondence  and administration.  As such they were [at this time] allowed to wear jacket and shirt etc, not the ‘sailor suit’.   

From his service record, in 1901 he was a Second Class Writer and had been awarded one good conduct badge – the anchor shows the rate and the chevron is the GCB.  He would have had a star with the letter W,  on his right arm.
The standing figure is a Chief Writer – he has the star and W badge on his jacket lapels. 

The Writer branch is still in existence in today’s Navy, see:

His service record is interesting – several short periods on ‘big ships’ – battleships and cruisers, with a spell in  China [1904-08]

I may have found the connection....  A Great Uncle is listed as serving on the Bellona in 1901 (Service record attched). I've also attached another photograph from the set. If my great Uncle was a 2nd Writer could he be one of these gentlemen with regards to uniform?

Navy's Floating Aerodromes. The Advertiser, Tuesday, 19th September 1939.

The article explains the history and development of Aircraft carriers, from 1914 until the sinking of Aircraft carrier HMS Courageous, by German torpedoing, in September 1939. The article explains Aircraft carrier development in the Royal Navy from 1914 to 1939 such as the difficulties involved and how vulnerable Aircraft carriers are to enemy attack. Aircraft carriers mentioned are Courageous, Glorious, Furious, Eagle, Argus, Hermes, and Ark Royal.

The article is in the format of 3 columns. Going to bottom of column 1 to top of column 2 and so on. In the case of the photos, it requires moving between photos in order to read the article in a logical order.

ASSEGAI was a shore base - a training establishment at Wentworth, Durban, South Africa during WW2.

G'day from Down Under!
At 78 years of age, I have just discovered through ancestry and DNA who my father was.  However, that is a story for another day!
I was able to obtain some of his military records, which indicate he was on Assegai from October to December 1943. Some of the details appear to have been redacted!  And I was hoping to fill in some missing details, please.
His name was Sidney Charles WEAVER, and his Register No was X 3242.
Any information would be greatly appreciated, or if you can point me in the correct direction so I can contact those who may know more.
Regards Harps.

It seems to show a Warrant Officer [ three buttons on sleeve and no lace rings and allowed a sword ]- from the 19th century - 1870-ish perhaps?

Unfortunately no such thing as a 'crew list' exists for RN warships.  An individual's Service Record should show the ships they served on

This gentleman is an unknown ancestor but I hoped that being able to roughly date and identify the rank of the uniform might give me an indication of who he is. Thank you in advance!
