Plugs,bulbs and nuts

Hi Pete

The nuts are sometimes confused with 6A/1755 as they are sometimes embossed with that Sec/Ref No, in fact the nuts don’t have a Sec/Ref No being 6A/NIV (Not In Vocab).

The socket assy is 6A/1755 and are used with a variety of bulbs for temp sensing.

I’ll send you an e-mail with what I have in stock in the way of plugs and temp bulbs.

Attached is an extract from AP1086 Sect 6A to AL/18

6A ref numbers

Hi Ken,

Attached is an extract from AP1086 dated 1966 which shows 6A/4420 equating to either KB153/03 or KGA-0403 but listed for COMET ONLY

6A/6680-99-4333780 is the current Sec/Ref for 6A/4420 and is in Nato Stock Number Sec/reference style.

Hope that helps.

regards
Dave

Very well done to all involved. Having visited the other week it’s great to see the enormous progress being made.

Best regards

Unusual pics of parts of WH983

The only ‘Canberra’ pics I have do not show the actual aircraft, but rather the remains of No1 engine taken on 19/11/76 at Marham. Pics are Crown Copyright.
These came to me via a retired work collegue a few years ago.

Hi Steve,

Can’t help on the A.Std designation. but:

The column designated Ref No is the RAF Stores Section and Reference Number (Section 28, BA/BSF bolts being later designated section 28D), therefore sec/ref 28D/7240 equates to part number A1/1E which is a MILD STEEL hex head aircraft bolt 1/4″ BSF. AP1086 lists this bolt in having a minimum length under the head of 0.58″. The 6 prefix for the British Standard series that the bolts were produced to, therefore the full part number is 6A1/1E.

The A1 series bolt was superceeded by the A15 series bolt in 1940 (with suffix Y for High Tensile and Z for Stainless Steel) ie. an A15Y/1E bolt having a sec/ref of 28D/7145.

The A15 series bolt was then superceeded by the A25 series bolt in 1962 for High Tensile and A26 for Stainless Steel, an A25/1E bolt having a Sec/Ref of 28D/12707, the full part number being 2A25/1E for example denoting the Aerospace British Standard.

The letter part of the part number denoting diameter of 1/4″ (2A25 being the British Standard for BA & BSF Bolts) and the 1 denoting plain length of 0.10″

Hope that helps

Best regards

Chipmunk

Was speaking to Dad last night about Chipmunks and other things and he said that the one pictured above came from Singapore and he bought it from someone in the Lee-on-Solent area.

He also came up with a couple of photos showing a ‘pile’ of wings he bought from Barry Parkhouse (when he had the Harvard in his garden!).

The other picture of the Chipmunk was taken at RAF Newton on an Air Cadet AEF trip.

Hope they’re of interest and I’ll have a look to see if I can find any other pics.
