Attached are a few pictures of some 40mm Crayford rounds.
The one on the left is a "standard" one for comparison purposes.
The one in the middle has a very unusual profile. When unscrewed the base is solid copper. I know of one other round idential to this one.
The one on the right is rimless. I know of 2 other rounds like this one.
Does anyone have any further information on these unusual Crayfords. The 2 rounds on the right do not appear to be standard and do not have any markings on them. I am assuming that as there are other similar rounds out there that came from completely different sources that these are genuine and not made up rounds (they certainly feel and look like real ones).
All inert and legal with nothing nasty in them.

No 2 is incendiary I believe. Herewith a sketch. In my time I have probably seen half a dozen, all with the copper base rather than the steel referred to in the diagram.
Thanks Norman, any thoughts about the rimless one?
None I'm afraid. The only other version I have seen was a 'regular' case with a projectile fuzed No 131 (the fast, fabric sensitive job).
do you have others of that quality showing other 37mm & 40 mm types ?
With one exception I only have diagrams from the usual Handbooks, Treatises and Textbooks. The exception is the Cart, QF, 1 1/4 Pdr, Practice (Mark I) /N/. I expect the gun is a little known bit of Navy ordnance; when the Royal Navy acquired what became HMS Swiftsure and Triumph in 1904 they inherited these guns (the two ships were originally ordered by the Chilean government and presumably this ordnance was specified by them).
The file is too big for BOCN but if you PM me with an email address I will send a copy.
Another Crayford type? Other than the nose it is the same as the standard HE shell.

Hi, the one in the middle is an incendiary type with the copper base to it - the strange thing about this one is the profile of the projectile. The projectile is securely crimped into its case. The other one I know of like this comes out of the case but is the same profile.
The one on the right is what looks like a standard HE projectile - the odd thing about this one is the case that is rimless. The projectile comes out of the case so it may not be the one that was in there in the first place however I can trace the ownership of this round back about 35 plus years and it was originally in a well know collection and I suspect its correct.
Hope this helps.
Dave, What base markings does the copper based projectile case have?
Hi BD, I like your variation - surely its not where a cap fitted?
Attached are the markings on the case that has the copper based projectile in it.
