Unknown maker of 23x152Bmm link for Soviet 2A7 and 2A13 guns

Unknown maker of 23x152Bmm link for Soviet 2A7 and 2A13 guns.

At first glance this link looks to be a standard Soviet 23x152Bmm link. However it has none of the usual markings but is marked: 23mm M6A1 D 97 AH.

Does anyone please know who made it and when? For some reason South Africa comes to mind when I look at it.

Thanks to both gyrojet and EOD, you have confirmed my own thoughts.
