MP38 u. 40 Pouch - Maker?

[Acez84]

I recently got this pouch, and wanted to know if it was 100% original.

I found a makers mark on the bottom left corner on the backside of the pouch. Its hard to read, but the lower two letters look like 41.

Can any of you gents identify the maker?

or

Gottlieb Singer, Leder-, Treibriemen-u.Lederwarenfabrik (otf)
