I believe I have a Mark VII projectile (WW I era) but I'm not sure. Can anybody assist with the identification? It had a No. 100 II-B fuze.

Are there any markings present? In particular punch marks?
Also the fuze data would be good to know.

It appears the MK VII had a different driving band.

Here some sheets I have on the 6-inch:

Thank you for the information. I have attached another image of the nose section. Also the round has a stamped "N 37" on the mid-section.

No other markings present?

I believe I've found the shell. I had originally misidentified it as a possible MK VII. I believe the shell is a 6 inch Shrapnel Mark IX. The driving bands match perfectly, the screws in the body, and the break between the main body and fuze. I was a little perplexed on the fuze but found information that in WWI the graze fuze (No. 100 series) was used on Shrapnel rounds. This round had the No. 100 IIB fuze.

What would be the point to use a graze (impact) fuze on a shrapnel?

From what I found out, the graze impact fuze had a minor (very minor) delay. The thought was that the round could go thru walls or firing shields before the fuze initiated. I don't believe this worked well so they started using a delay fuze on the shrapnel rounds.

Indeed an odd thought.

There were no more markings on your projectile than those you listed?

Hello,
Markings of designation are usually on the base (6IN MK..)
You're shell is not a shrapnel shell. Shrapnel shells have thin walls and twisting pins on top. Head is not screwed on body.
This shell is definitly a HE shell. HE shells were made in one piece or with head screwed.
"X", you show early common lyddite shells with fuze with GS thread (and not 2in hole). You can find same Mk on different 6in shells, Lyddite or HE, and depends on guns used.
Lot of Mk were made, exceed MkXX.
Could you give length without fuze ?
