Looking for information on fabric belt, clasps stamped oLc

Belt is about 120 cm long with aluminum clasps at both ends.
The clasps are clearly stamped oLc.

I suppose it is a multi-purpose belt but I have no clue regarding when and by which factory it was made.

 

The belt is worn over the shoulder as can be seen on the picture down below. I think it's Bundeswehr belt but let's wait for someone who's the better expert.

 

The above is a leather belt.
The one I am referring to is made of fabric.
Since my post I got confirmation that at least the aluminum clasps were made by oLc (Overhoff & Co, Lüdenscheid).

 

I couldn't find the photo of the fabric belt in wear so I put the leather one instead. The difference is that the leather was worn by officers and during parades and the fabric one was probably for an every day or working use.
