I agree the Charlie's answer but just a remark for Charlie: they were 100 mm in french Army, some marked "10 cm" (because french Navy called "10 cm" the "100 mm" guns during some years): it is the 100 mm modèle 1897 TR, a modern coast gun on static carriage but some barrels were mounted in old 155L de Bange carriages as a stop-gap emergency resolution in the last months of 1914.They were strange guns with very long barrel on old carriage but the range of 14.500 meters was good for firing against long range german guns before more modern french guns and railway guns were in service. Yours sincerely, Guy François.

10cm doesn't sound like a French calibre to me. There was an Austrian M14 10cm howitzer which saw extensive service throughout WW1 (and afterwards) which might be a candidate for your cartridge. The German 10cm Haubitze M98/09 used a much shorter cartridge than your example.
If you don't get a definitive identification on this forum perhaps the people over at http://www.bocn.co.uk/vbforum (British Ordnance Collectors Network) can help.
The shell casing may not have been cut off. The M14 howitzer used a separately loaded projectile with the cartridge used for obturation and the primer. The M14 had 6 bags of propellant in the cartridge which gave a fair amount of flexibility of propellant charge. There was no reason for the cartridge case to completely fill the breech space up to the projectile as would the case for fixed rounds. The German 10cm cartridge case was even smaller, only about 9cm high.
...bit of digging around - I found an image of another M14 cartridge on the axis history forum (attached).
Regards,
Charlie
Edit: found the dimensions of the M14 cartridge - 100 x 132R - if your cartridge is about 132mm high it hasn't been cut down.

Thanks to all. I was going down the austrian road in my research but I just could not quite figure out if the stamp was an eagle. It is not clearly stamped.
So the casing only held the powder? The "bullet" was separate?
I thought they were all integral like todays rifle shell: lead inserted into a brass casing.

The projectile was separate and was loaded in so the drive bands engaged with the rifling. This is still done today - you can see the separate loading of
projectile and propellant in this video clip - http://www.youtube.com/watch?v=uoZ1900AhDU.
The cartridge case had the propellant in six bags - to fire with reduced propellant loads the appropriate number of bags were pulled out of the cartridge case before loading it.
Fixed ammunition like a large rifle round is useful for guns where you want high rates of fire and have no requirement to alter the muzzle velocity of the gun - anti-tank guns are an example. High angle guns like howitzers need the capability to control the muzzle velocity of the gun by changing the amount of propellant.
