Researching the Haneka 4x81 German Issued Rifle Scope

Hello,
Looking for research information on the

Haneka 4x81 German Issued Rifle Scope

So far I have located information on the Zeiss, OIGEE BERLIN 4X26, Schmidt and Bender 4x36, and other German scopes. Not finding any Haneka information

Any assistance would be Greatly Appreciated.

It's not Haneka - it's HAWEKA. The 3rd letter is a W, not a curly N!
