Good old Phil.sword scabbard; 4 what type??

[Indianajones]

Hi all,
picked this good old Phil.scabbard up and wonder to what type of sword it belongs. Perhaps one of you knows . .??

I reckognise it being a quite old -1850's- and rarer type of scabbard as these look quite 'dull' and 'unaddorned' and therefore often seperated and thrown away? In the RMV in Leiden they have a sword with a similar type of scabbard which is -I believe- a bit broader, as is the knife.

In matter of fact this example also was in a box together with some rubbish and shells. No sword to go with it, (I asked ofcourse!)

Am looking forwardd to your replies!
