I have been looking into some tooling required for my project and have come across some Drawing/Part numbers in the AP’s. I have come across A.G.S, A.Std which often cross reference with the stores ref (26BX or BV for instance) but in the case I am looking at they are referenced my T.D. 1050/# or M.###. Some have a corresponding A.Std reference and some do not. The AP’s refer to these as drawing number, part numbers or tooling depending on the circumstances so I am a little confused.
Has anyone ever come across those sorts of references? are they an internal number or do they refer to a particular manufacturer? The particular numbers I am after are M.960, T.D.1035, T.D.1050/## and M.1548. They are tooling items and are used for tube squaring…I am hoping that they will lead to a particular manufacturer or perhaps these particular drawings are still in existence.
Long shot but it is amazing what knowledge is on here 🙂

Hi Bruce,
Thanks for the reply, I knew that Guy had reverse engineered one of the machines (T.D. 1035) and had based this around some of the A.Std rollers found in south africa (I believe). I have a copy of many of the A.Std items but this new numbering system was something I came across digging through the AP’s. I hadn’t come across this before and was wondering if it was particular to the manufacturer of the tools rather than the design authority (Hawker) or the RAF stores reference (the 26B number)? Sometimes some of the original drawings from a manufacturer still exist and I have even found some in local libraries when the companies archives were donated.

All the tube squaring info was decoded by Guy Black/AeroVintage some years ago – indeed he found an original squaring machine, IIRC in India. It is still in regular use.
The A Std’s are proprietary Hawker drawings, and were often used on many different a/c.
