I have never seen an asnwer, but have found some information in the book 'British Military Landrovers; Leaf-sprung Land Rovers in Military Service' by James Taylor & Geoff Fletcher. The ISBN number is 978-1906-133-658.

Page 80 about the Series IIa mark 9 (109") states that no official records exist for the Royal Navy. For RAF and Amry these records are available, so the table on that pages only shows some fragmented information, without mentioning the registration number and chassis number you mention.

Since 2015 I am researching my father's past in the Royal Navy. He started his career as a Boy Signalman in HMS St. George in 1943 and retired in 1971 with the rank of Captain as XO of the Malaysian Navy (a post provided by the RN till that time). In between he has sailed in a cruiser, a variety of A, S, and T-Class submarines, including two Depot ships, sailed in Aircraft carriers and frigates and in a coule of shore base assignments.
In that research, the shore base assignments are the hardest to fin information about what he did (I found one NATO STANAG with his name on it...).
Information about what he did when he was appointed to a ship or boat is a lot easier. The National Archies in Kew have a lot of ship's logs which provide ample detail about the whereabouts of a ship and what happened during that time.

To make research easier for other people I compiled a document which helps to extract information out of the ship's logs for people with less experience.
This also includes means to find out where a ship has been on a certain time and date. For certain ships, I have been able to record the trips on Google maps with amazing accuracy (triangulation with errors less than 30 feet of margin...).

I hope people can use this information in the attachment and am curious to receive comments and corrections.
I also have a list with reference points, but that list is to big to be uploaded (1,3kB).

It was up to individual owners to fit their ships with weapons – that would inevitably mean what they could afford.
   
Lloyd’s Register of Shipping shows the armaments.  For this period they may be found [you will have to scroll down the page] here:

https://hec.lrfoundation.org.uk/archive-library/lloyds-register-of-ships-online

– see as example =
https://archive.org/details/HECROS1780/page/n7/mode/2up

Column 7 shows the name of the owners, and some entries also shows the armament

According to David Syrett [Shipping and the American War],  which studies the hiring of  ships to transport stores or troops to North America, they initially had difficulty in getting shipowners to arm their ships at all.    This was because it would contravene an Order which prohibited the export of guns and ordnance stores to America.   Syrett states that most ships going to America 1775 – 76 were unarmed.   After 1776 an Order in Council lifted the restriction.

 After this, for merchant ships hired for service as transports or to carry  stores for the Government, then the Admiralty did lay down a minimum – owners should arm ships with “at least six carriage guns of six pounders or less bore, according to the size of the ship”  and later  [1779] allowed shipowners to fit carronades ‘not less than 12 pounders’
Looking  at the details of those vessels either taken into Naval service, or hired as a cargo/troop transport, then it would seem that the usual calibre was 4- or 6- pounders, although some were able to carry 9-pounders.  The number carried seems to have increased, but would obviously depend on the size of the ship.
 For examples, see:

During the American War of Independence, with what ordnance were merchant ships armed (to protect themselves from Aermican privateers)?

I am researching the Hallamshire battalion (York & Lanc's Regt.)
Seeking information on the landing craft that carried them to Gold Beach.  They embarked on D+3 in 5 LCI(L)'s from Newhaven Hard and disembarked on maybe Gold Jig but not sure.  What flotilla and craft carried them.

While waiting to move from Newhaven, the Commanding Officer and a couple of others spent their free time producing a battalion battle flag from scrap material.  The flag flew from the mast head of the LCI all the way through to Germany at every Bn HQ.

Any help appreciated - than you.

I am planning on building a large (1:96) model of HMS Warspite (03) one day and have busied myself lately doing research so that I can build her in as much detail as possible.

The obstacle I am coming up against is that although I have several authoritative books on Warspite, some of which contain construction plans, when they show a standard product, such a rigging insulator or an electronic steaming light, no detail is given but a note will say something like 'patt. xxxx' referring to an Admiralty pattern number for that product.

Also, any aerials are usually referred to with a code such as 48C or 49C which I am guessing is a reference to the material and thickness.

I have tried to find a reference or index for these patterns and codes but to no avail so my question would be: Where would I be able to look up Admiralty pattern numbers and see detailed drawings or descriptions of the product?

I am modelling Warspite as she was in early 1942 so the references, if they exist will be from this time period.

Any help appreciated.

I have come across this excellent photo of Submarine H33 and crew in what must be 1926-27. The two officers are Lt C deS Brock (in command -right) and Lt Richard Sheridan-Patterson [his record shows  as with H25 at this time..]. Maybe at Portland with 6th Submarine Flotilla??

The Royal Navy and the Falklands War.
David Brown (Head of the Naval Historical Branch)
First Published 1987.

I bought this secondhand book at the RSPCA opportunity shop here in Adelaide, South Australia for $3.

Information from the front cover overlap.

In this book David Brown, head of what was formerly the Naval Historical Branch at the Ministry of Defence, tells in full for the first time the extraordinary story of how the fleet was assembled; of how merchant ships from luxury liners such as the Canberra to cargo ships of every description were 'Taken Up From Trade' and, in a staggeringly short time, converted in to their new role.

A Google search of this book title brings up a wide range of different prices and information about the book.
