Question on double date DWM

[romer12]

it looks like the buckle type closure strap was changed to strap going into slotted opening, like the artillery holster type.
I was thinking the GN on holster was 'gelnhausen' near manheim (I think). I don't have macro camera, so can't get to close. the finish for the middle toggle is exactly equal to the front and rear toggle. don't appear changed ????? I'll have to try and take more pics of top and holster. Holster v.good condition although well used. looks like someone in the past dyed it black (as I know germans did during WW1) with a very nice finish, like patten leather. the 2 mags are also matching.
