I have another oddity on my bench.
There is no glazed card. The cordite is in a bag with a string tied top.

Alan ages ago I posted a pic of a MKVII round I think it was a MW (Munitions Welshpool) it had a roll crimp instead of the normal stab crimp I've never seen another one and I never got an answer back from anyone regarding so did they trial roll crimping say for ease of production.
If anything it would have been an Aussie thing I'll have a scrounge and see if I can find the picture again and post it cannot vouch for quality as I only had an I-Phone IV at that point I upgraded last year to an 11 I think!

Postscript,
I found the round on my desk so took some better pics, you can see faint stab marks but the roll goes right around the neck at the same depth so maybe a machine adjustment don't know anyway something to discus.
It is a ball round not a reload I was correct it is a MW VII 44.

Blown up a bit it looks like there are three crimps, if the points indicated by the blue arrows are indeed each the start/end of a crimp.

The profile as indicated by the yellow arrow is noticeably deeper and more "V" shaped that the other photo where it appears the position of the case in the photo is such that we are looking at the area between two crimps?

Badly worn dies or improperly adjusted machine?

I reckon Surpmil your right, perhaps the stabs wore worn and it colletid the neck instead of the indent stabs being performed, it stands to reason with the millions of rounds being churned out that these anomalies would occur.
How many got through I wonder as Q/A inspection may have ditched them as not being as designed so may alter the way the round performed (It would not really) but someone's life depended on how it did work so it they would have been binned it.

Bindi2 be good to see a pic of that one!

In the UK every single round was inspected by MK1 eyeball and individually weighed, but I don't know it they'd have picked up your 'ring'.

6-8 'lines' per shed, how many sheds per manufacturer ?

Notice the overhead belt drive for all the machinery.

That's how the industrial revolution was powered.

We have a small engineering company in our local village - I was hunting around the back of some of the buildings and came across one of the original buildings from the 1600's.

I was talking with the owner who was explaining that the site and buildings was the original 300+ year old blacksmiths forge.
There was a big steel shaft going thu the roof one one building, out and thru the next building.
In one building was the original forge and a 'power hammer' that was driven by a belt driven from a pully-wheel on this shaft.

It is interesting to see 100s of years old technology - not in use but still installed and which could be made to work.

A friend of mine (who recently passed at 89) spoke about setting up belts for machinery - he showed me old catalogues (I'm sure I ended up with some) and IIRC old copies of Machinery's Handbook showed the proper setup of belt drives.

Industrial Antiquity - Line Shaft Pulleys and Belting

[CINDERS]

In the late 60's on school holidays, I used to roustabout for my Uncle who was a shearer the o/head gear was run by belts driven from an electric motor in turn driven by my Uncles single cyl Lister engine he towed in a trailer behind his Landy.
There were also 2 vertical grinding discs driven by belt from the lister engine in the trailer one coarse one fine the coarse side for your combs and the fine one for the cutters.

[Surpmil]

Sounds like your uncle had a Lister "Start-O-Matic" generator Cinders, or something like it. Lister clones are made in India these days, but AFAIK they've never made the full rig with generator-starter and panel attached.

I just dug out my copy of Machinery’s Handbook 21st edition, revised, 1981 print.
There is an extensive section on pulleys starting with flat belt drive and applications and design of leather belts through to all the V belt types and uses. Pulley manufacture, uses and ratings for wood, cast and machined pulleys.
It doesn’t go into design for long shaft power transmission systems.
