"o.u.b." Marked Sling??

[Captain Emo]

I recently picked up a sling for my K98. The only marking that I have found on it is "o.u.b.". Can anyone identify this marking? The sling seems to be vintage cross-hatched leather.

Thanks in advance for your help.

Hi

You have a sling with a so called tree letter coded; and the code "oub" referring to the below mentioned maker.
Anton Jelinek & Sohn Leder-Fabrik in the city of Gross- Meseritsch nowaday's location is inside the Czech republic. Anyway not a maker you see everyday.

Nice find.
