    Thank you for all your helpful suggestions.
    While there is a direct flight to London from where I live, Google advises me I live 14470km from the British library.
    While I understand what they are trying to achieve, protect a copyright holders IP, they could have provided a more detailed explanation.
    The catalogue is 70+ years old and the company that produced it is long gone.
    Looks like I will be calling the home country soon.

    I have what you require. Currently travelling so can not provide documentation for another 10 days or so. PM me and I will send when able. Documentation advises current values in various test modes and general how to use.

    Just found a comment in the Mk4/7 catalogue which states “Mark 3 plugs and sockets have now become obsolete and should not be considered for equipment under design. In all instances the Mark 3 range has been replaced by Mark 4.”. There is a similar comment regarding Mk5/7 connectors.

    P & P good info.
    I have been looking into breeze and Mk4 connectors for a little while now and occasionally connectors are referred to as a Mk3.
    Given that it is not a Mk 4 or later, is a Mk3 a “late” version Breeze?

    I have data from 1941 showing the Breeze Corporation making connectors to AN9534 (which become MIL-C-5015 in time). So yes, Cannon connectors.

    This was a position in the Ministry of Supply in 1953.

    Count me in for a copy. I asked a question on the forum about 3 weeks ago on this subject.

    As to the question of paper or digital, digital makes the potential audience able to access a given book sitting on a dusty sleeve much greater.

    I personally digitise the majority of the information I have available so it is ready available for answering questions that come up on this forum.

    We do have to give some thought as to networking, in relation to how a very interested individual gets to know that another has the book/plans/drawing/brochure they have been trying to locate for years.

    Perhaps we should start a “rumours” website. As we go somewhere and found stuff we just announce it for any one who follows that is interested. For example I got my hands on the RAF AP on Hamilton Standard propeller parts from 1945. Totally unexpected, and I am sure others may be interested in that find.

    Since I live in Perth and have tried to gain access/determine what is held in the Museums collection without success, how do you get to handle these precious books?

    I have the unit listed as fitted to the HP O/400. No doubt there will be other types as well.

    I find I have a copy of TN.135, dated 12th march 1945, “The 12 hour nitriding of crankshafts, airscrew shafts, connecting rods and minor components.” I do not have a copy of the other instructions I listed above.

    I find I have a copy of T.N.109 issue 2, dated 3rd June 1942, which is a special instruction issued by Bristol for “the 24 hour nitriding of crankshafts, airscrew shafts and minor components.”

    I will PM you with the details.

    Further instructions for other parts that are listed on the document are:

    T.N.43. Nitriding Valves and the preliminary Copper and Nickel Plating.
    T.N.44. Nitriding Steel Cylinder Barrels.
    T.N.86. Nitriding Poppet Valves by the method involving reverse etching.
    T.N.94. Nitriding Cylinder Sleeves.
