[Antoon]

In ORBs and other RAF documents from WW2 are abbreviations used in relation to the fuzing of aircraft bombs.

Who know what the following abbreviatons means:

NDT
MLD

Other abbreviations are also welcome.

Hi Antoon

Can you please give examples of both?

Post some examples next week.

The most NDT have 0.025. So I think that this means Non Delay Tail with a 0.025 sec delay detonator No.49 Mk I (with No. 28 Tail Pistol) or No 51 detonator (with a No. 30 Tail Pistol).

Hereby two examples of RAF forms with the abbreviations.

​

Found the abbreviation for MLD. It means Mixed Long Delay.​

​

Found also the abbreviation TD 025. I think it is Tail Delay 0.025 sec​

Hi Antoon

I think that 'TD' means Time Delay. This relates to the No 49 or No 51 Detonators (delay 0.025 secs) under the long delay Pistols.

I hope this helps
