Good day: I’m wondering if any one has any info on a Grundig ACR OISeye that was given to me. The eye is circular but opaque(white) not clear which leads me to the conclusion that it is linear although it does not say anything but the name, the serial # and made in the E.C. Now would it be the same as say a Digiwave? Or is it NFG, I’m just curious and know there is someone, or a whole lot of folk on this site that know. I Googled it but got nowhere, couldn’t find it listed. Thanks in advance. Father O’Reilly
