NBR Axlebox details

    Could anyone help me with dimensions and/or detailed photos of NBR wagon axleboxes?

    I've been asked to produce a 3D CAD master for Gauge 3 - so the details will show.
    I have a somewhat unclear GA drawing, and a couple of scanned photos of varying quality.
    I've looked through the NBR Study Group lists without seeing anything obvious.
    The SRPS have a wagon with these axleboxes (8 ton double ended Mineral Wagon NBR No.65013), but it's a long way from me.

    Any other sources or pointers also welcome.

    Do these help? 8 ton and 10 ton versions of the NBR round bottom axlebox from GAs in John Hooper's Wagons on the LNER - North British No1. Should be enough dimensions readable to scale from the drawings.

    You might be a long way from Bo'ness, but it's almost on my doorstep and I will be there on Sunday so I could take some close up pics of the axleboxes and possibly a dimensioned sketch if time permits. Would that be of help?
    Regards

    Andy, I think it would be really good if you could respond to what are now two very helpful responses to your question.

    I appreciate you mightn't yet have seen Martin's reply.

    Overseer,
    I think the GA scan I have is from the same source, but your scans are clearer, so thank you.

    Martin,
    A few minutes of your time to take some close up pictures would be excellent and much appreciated. A sketch and key dimensions even better. Previous experience tells me that taking good shots of black, and often dusty, bits in a dark place under a wagon can be a challenge!

    Simon,
    Yes, both responses are very helpful and appreciated. I've only just had time now to response though.

    Looking through the photos in the North British wagon book it is clear that the 8 ton axleboxes were marked in raised letters "N.B.RY" (with the Y smaller over a horizontal line) above "No. 3". I couldn't see a clear image of a 10 ton axlebox to work out what number they were, but the photos show the larger 16 ton axleboxes were number 10.

    I'm of the opinion that the NBR wagon in the photo isn't what its first appears. The Lettering is that of a NBR open but according to the diagram book they didn't have any double ended wagons. Double ended wagons like that one were built by the G&SWR as Ayr docks didn't have wagon turntables. Moving on to the axle boxes. These are a tricky one as they could come from a number of different pre-1923 sources. The Cally, Highland, Great Northern, Great Eastern, Hull and Barnsley, to name but a few , all used this type of grease axle boxes.
    So in conclusion
    Livery: NBR
    Body: G&SWR
    Axle Boxes CR/HR/GNR/GER/HBR

    Marc,
    Thanks for your input.
    I think it is widely accepted that the SRPS wagon is a 'bitsa' - and the caption to the picture (on the SRPS site) does say that 'NBR' is cast into the axleboxes so the wagon was liveried to match them, despite the body not being of NBR origin.

    Martin's plan to get some detail photos a couple of weeks ago was thwarted, so I'm waiting patiently until his next visit (plenty else to do in the meantime...).
