Unknown Swedish 11 mm, 37 mm and 47 mm shell cases

[Hoeksel]

Found on https://digitalmuseum.se this box with mostly unknown shell cases. It contains a set of 11 to 47 mm shell case and projectiles. The set is granted by King Oscar the 2nd of Norway and Sweden in 1883. On 1 image I see "Palmcrantz" so I think it is safe to assume this is a set of 1883 or earlier dated Palmcrantz/Nordefelt rounds. I still need to dive in if I know any of these, but some I have never seen before, no time except to quickly share this and collect more information.

Box contains (left side):
- 47x293.7 mm Nordenfelt M1895 (strange as box is given in 1883)
- 1,5 inch Nordenfelt three variations (37x125,5 mm, 37x158,7 and 37x197 mm).
- Not yet dived in this probably 1 inch round.
Right side:
- 2 smaller rounds (no effort taken yet to find them)
- 0.45 inch multi-barreled (4 or 5) shotgun.
- 1 inch Nordenfelt.

I checked my references and based on my recent experience the measurements done by the museum are not very reliable.

For the Swedish 47 mm M1895 I have 47x300R and the neck looks different as well, plus a M1895 cannot be in a gift from 1883.
For the British Nordenfelt 37 mm 1.5 Pounder Mk1 I have 37x123R48 and I have 37x126 for the 1.5 pounder Nordenfelt, this matches the Swedish 37x125,5.
I do not have anything close to the 37x158,7 or 37x197.

Looking on the website again I found:

The 25,4x95 is for a 4-barreld "shotgun" so I assume "shotgun" is a wrong translation from Google or the museum and actually means revolver gun/cannon.
The 0.45 inch shell case (my expertise starts at 12,7 mm) is then most likely also for a Nordenfelt mitraileuse/revolver gun.
The probably 1 inch round is a 25,4x123 for a 3-barreled Nordenfelt.
One of the smaller cases is a 9,6x65,2 mm for a 2 or 5 barreled 0.38 inch Nordenfelt.
The other smaller case is a 11x59,8 mm for a 4 or 5 barreled 0.45 inch Nordenfelt.
The 11 mm is a 11x90.8 mm for a 4 or 5 barreled 0.45 inch Nordenfelt.
The 37x126 and 37x197 are fortress machine cannons, the 37x158,7 a 1 barreled Nordenfelt.

While looking I found a lot of dummy/sub-caliber rounds that looked like Nordenfelt as well in many calibers, but all lacking proper dimensions ;-(.

Search words I used: Patronhylsa, Nordenfelt, Palmcrantz, kulsprutor. I found a lot of spelling issues so many goodies are hidden a bit. Plenty of cool stuff to see, too bad there are so many errors and lacking information.
