My mate Ron has these 4.5 cases and a 4.5 dummy that he wants to find some information on, as he has been unable to find anything on them so far. One case and the dummy are Australian made (ADI case, MBO dummy) and one case is British (RLB Birtley).
The usual 4.5 case (for MKS 3-5 GUNS) is 114 x 640R, is separately loaded and has the mouth screwed for a metal or plastic lid plug. These brass cases have full necks and are 114 x 693R (RLB) and 114 x 698R (ADI). These longer cases do not seem to be allowing for extra metal before threading the mouth, but appear to be a fixed version of the 4.5 Mk 3-5 case. i.e. Interestingly the fired British RLB case has crimps in the neck indicating a fixed round. As a fixed round this would be very heavy and probably required mechanically assisted loading, indicating Naval use.
1. Wood and steel dummy
640/644mm overall length, 465mm to shoulder. Finger/grab cut-outs at base.
Lightly etched into base:
MBO 3/1960
INO No. 61205 A
REPRESENTATIVE CASE & LID WJD (?)
No. 1
MBO = Ordnance Factory Bendigo, Vic (now Thales).
Appears to be for a 4.5 Mk 3-5 Gun, but how is this dummy used? Is it possibly a packing/container gauge, or is it a drill round?
2. British 114 x 693R case (4.5 fixed round?)
Headstamp: 4.5 14051 -06 RLB 5/86 232
Primer:
N44 MK3 BN028 85
OOO
GD 1085 421 AA
What is this round and which gun was it used in?
3. Australian 114 x 698R case.
Ron has 2 of these cases and they are new/unused, with no primers (or mouth crimps).
Headstamps:
4.5 IA 4.5 IA
T598/100021 T598/100021
ADI 0206 004 ADI 1005 002
ADI = Australian Defence Industries, Benalla, Vic.
What is 4.5 IA? T598/100021 is the same on both cases is this a gun or case designation?
Is 0206 004 Feb 2006, Lot 4 and 1005 002 Oct 2005, Lot 2?
Any information on these cases, the guns or ships appreciated. Cheers.
