Double magazine pouch by Akah?

[Richard]

Recently I got a double-magazine pouch for the parabellum - marked "DRGM/Akah" on the back
(marking very thin - but you can see the Akah-logo on the pic)
The pouch sits on a leather slip - that is marked D.R.G.M. and "33" - never seen before.
A friend thought it is, may be, a persian one, with faked marking -
but in comparison with a persian pouch it is a little bit shorter (see pics).

Have you seen such a pouch before?
How was it used/fixed with the slip??
