What do these base stamps mean?

[morser124]

Can anyone tell me what these base stamps mean on this 4.5inch british case please

4.5 14051-007 RLB 12/89 261

and then what look like 3 'C's spaced far apart.

Thanks

RLB - Royal Labs, Birtley. 12/89 may be a date. Sorry I can't help with the rest. Is there more markings ? Nice casing.

Hello. thanks for the reply. Shed some more light on it for me. I have another case, complete with a projectile, it also has the RLB crossed out. Ive no idea what projectile it is though. Its been restored by the look of it. The fuse has no thread and its held in place by a screw into a bit of wood which has been pressed in the projectile. Its not the best example but it was cheap so i bought it. Very nice star round you have also.
