Yes very wise to keep away from the dreaded lead pencil :shake:

Pete but are you sure? If you get it the wrong way round it will sort of work as you will get a spark either way round. But if you end up with a "positive spark" you will get poorer performance & more wear from the rotor arm. If you have the wrong design of coil for the earth you are using & wire it up to get a "negative spark" you will have a reduced HT by about 600 volts. This is because the back EMF of about 300 volts from the primary as the points open adds to the HT. If it is the wrong design of coil despite arranging it to give a "negative spark" this 300 volts is of the opposite polarity to the HT so it subtracts 300 volts. So the net result is you are 600 volts of HT worse off using the wrong design of coil.

Looks like Vocab Ref 6B - Aircraft navigation equipment, accessories & unit servicing.

Terry does the blue plate give the CAV number?

Yes see what you mean.

I have the Technical Handbook for Q2 that dates it to 1956.

Rich I would check lead INS that supplies voltage to the fuel & temperature gauges that is taken from INS coming from the switchboard. Somewhere I have all the part numbers for the ram if you need them.

You would be very unlucky! I have never seen the cables alone, although they were demandable as LV6/MT1/AU/LK/34473

Some earlier rates:

Wayne in my evolved master list I have that KL2762 is the cup in the repair kit KL71490. It is likely that KL71475 is a kit rather than just a cup? Unfortunately my Lockhead/Automotive Products Co catalogues are packed away & I can't see what the kit comprises. But are these NOS by the looks, would it not be better to buy new from John Walker & probably cheaper?

Here are some of the prices attained:

That's an interesting chart but is quite a simplification, including the misspelling of 'serjeant'. Compare for example the ASC lists. Rates of pay are contained in these & allowances should be made for the allowances of their various kinds.

Well I have a War Office publication dated 1807 that refers to General staff.

What a super clip. I remember some years ago metal detecting at Crow Point in my own little world with headphones on suddenly confronted by one of these. It came ashore directly in front of me sped along the beach then back into the water obviously much quicker travelling on land than against the tide! Unfortunately before the era of phones with cameras.

It is often someone carefully observing on the sidelines that spots the crucial clue that the lead poster doesn't quite get (Didn't see you at GDSF this year, did you go?)

Here is the bit about the C in C Then C in C abolished I don't have KR but here is QR (ER) (I doubt if the actual duties have changed much) But looking at QR (VR) 1859 the MS was already under control of C in C! So did MS pass out of C in C control & then back again in 1901? Or did the seventeen Royal Commissions, eighteen Parliamentary Select Committees and nineteen War Office Committees actually forget who controlled the MS? Makes you wonder!

Yes well done! I think Richard must have fallen asleep at the keyboard I thought he was about to clinch it. Although he did get 75% of it early on.

Nope Richard it is a post.

Nope Richard not that.

Sorry missed you first time. Nope, but good suggestion.

Nope although the first bit is correct.

Good bit of research there Richard. Its all part of that general buzz after the Crimea that focussed the attention of seventeen Royal Commissions, eighteen Parliamentary Select Committees and nineteen War Office Committees! Although I will seek to show at the end that something in the letter may be not quite right.

Pretty good going Richard that's 3 out of 4 just need to rethink on MS

Nope Wally this is Army.
