    What means R.L.B.?

    Hello,

    what's the meaning of this abbreviation: R.L.B. ?

    I found it on a british 4.5\" naval case of 1970.

    One source said that it means: Royal Ordnance Explosives, Division PLC Co. Birtley/Durham.
    But as I know from other listings, this factory used the abbreviation ROFB.
    So I'm a little bit confused. Maybe someone can help.

    I'm also looking after a (more or les) complete list of the british RL and ROF factories until 1970 and their codes/abbreviations.

    Regards

    I thought RLB was for Royal Laboratories.

    Cheers,

    Re:What means R.L.B.?

    just been doing a web search and keep finding that Royal Laboratories Woolwich closed in 1967,Defenders RLB cartridge is 1970 and just looked on my RLB 105 and thats dated 1982,So im now wondering if upon closure of woolwich the RLB stamp was used by Birtley

    Re:What means R.L.B.?

    well, I did a web search too and found this list of ROFs:
    http://www.answers.com/topic/list-of...es?cat=biz-fin

    It's right, after some closing downs from the late 1950s to the 1970s the remaining ROFs were privatised in 1984 and became Royal Ordnance PLC. In 1987 RO PLC was sold to BAE Systems.
    Look here:
    http://www.answers.com/topic/royal-ordnance-factory
    and here:
    http://www.answers.com/topic/royal-ordnance

    Poorly the list mentioned above says nothing about the kind of factory Birtley was resp. is. But it seems that there was no Explosive ROF or a Filling Factory. So I developed this theory: Birtley made the brass cases and delivered them to the RL Woolwich and other ROFs. Like a \"house-manufacturer\" for the RL the cases were marked RLB. Through all changes of ownership this stamp stayed in use.

    Just a theory. Post your pros and cons please.

    RLB stands for Royal Laboratory Birtley then it was change to ROFB
    The purpose of annealing is a heat treatment they do to case & projectile before they draw them out in there required shapes
    I?ve attached a photo of a of the draw stages of the 5.56mm NATO cases in made, it is annealed to stop the brass becoming work hardened & brittle during these stages.

    Hello HarryG,

    thank you for your reply.

    Do you know when the change was? Or could there be a re-change from ROFB to RLB?

    I have RLB on a 1970 british 4.5\" naval case , as I mentioned above.
