Looking for a list of DRG numbers

Yes – looks like a pickup – probably for the outer wing joint.

Hi Nils,
As I mentioned before, I do not have a detailed knowledge of the wing structure of the Wellington. As you can see from the list that I sent there are many different sections. Inner / Outer..Upper / Lower mainplanes etc. The list was drawn up in the 1930s to cater for biplane construction hence the many mainplane sections.

In this case Top Outer Main-Planes means the section of wing outboard of the engine nacelle on the Wellington. The photos look to my eyes like a joint in a main-spar boom. So could well be where they join the Inner section.

Hopefully there is a Wellington expert out there who can confirm this. Might be worth you starting a new thread with a ‘Wellington’ title, to attract a suitable expert!

Chumpy.

Chumpy,

thanks for the list !
Here I have a large part from downed Wellington. The part number is 28507.
In the list is this number “TOP OUTER MAIN PLANES”, what does is means exactly ? Could the part on the photos fixed on the wings ?

Regards
Nils

Thanks for the interesting informations !

@Chumpy
can you send the complete list of codes you have show in your posting ?
I have a lot of Wellington parts with part numbers from some crash sites. It would be great to can identify the locations on the Wellington !

@Mark
thanks for the link ! I will try to contact the museum,maybe they can help with more informations of this data plate.

Best regards from Kiel, Germany

Whilst I dot not have a detailed knowledge of the Wellington, the data plate is ‘standard’ Vickers. Similar plates used on Spitfires, the Supermarine company also using the Vickers method of part numbering.

As previously mentioned the first three digits denote the aircraft type. The next two digits the particular section of the aircraft structure eg ***18 Tailplane…***44 Petrol tanks.

In this case the ***03 denotes Top Inner Main Planes, the last three numbers denote the idividual part or sub-assembly.
In the case of Spitfires this sort of plate was only applied to major sub-assembly items, hence the ‘61424’ serial number, so I suspect the same for Wellingtons.

Thus the full Drawing Number for this item is 28503-808.

The ‘BQ3’ is a factory date code, again similar found on spits.

Cheers, Chumpy.

Nils,

It would seem the part number for this plate is 03-808, while the 285 confirms it as a Wellington, as per the parts number list in the link.

The serial number 61424, and the particular part relating to 03-808 might be best enquired with the Brooklands Museum who have an intact Wellington mark 1A which they restored after recovery from Loch Ness, I suspect they should be able to decifer the name plate you have from their reference material?

Guys,

thanks for your reply.
I have a lot of aircraft part lists and manuals, one for the deHavilland Mosquito too. I´m stupid, because I have not mentioned that I´m looking for the details of part numbers (DRG´s).
On interest are the definition of the number which digit referred the part.
The first three digit on Vickers parts referred the type of aircraft, but which of the following digit or digits referred the part self? The code on Handley Page Hamden aircraft part numbers is easier, because the letter show here on which section the part was installed.

Here a data plate from Wellington crash site. Here are on interest the code for the date. Means the BQ3 the third quarter ?

Regards and sorry for the sad formulation on my first posting 😮

Nils,

I think this is what you are looking for:

DRG No

There will be many here more qualified to contribute than I, but I am used to DRG No being an abbrieviation for Drawing Number. If stamped on a component, it would refer to the design drawing that illustrated that particular part. The make-up of the number would vary across different manufacturers, and indeed in the case of de Havilland there have been several different ways of numbering drawings.

I confess that I am not very familiar with data-plates, but it seems a reasonable assumption that these would have a drawing number requiring specific dimensions and content etc as much as any other placard, notice or aircraft component.

This may not be helpful, or even correct! Hopefully one or more of our esteemed and knowledgeable colleagues here is able to assist further.
