GERMAN BOI STROP

Hi guys. I purchased a German BOI NOS still in the packaging leather strop from e-bay. It arrived from Bulgaria today and I wanted to ask if any one have any experience or any knowledge about the strop or the manufacturer. It has a leather handle, linen back.

Is BOI still makes strops?
Is this a horsehide strop or not?
Anything at all?

BOI no 1610

Thanks.:shrug:

Sorry, never heard of it. Maybe you could post pictures?

I have this strop too.
