CD,
Hensoldt was among the first European scope to show up in the US, along with Zeiss. Hensoldt is a very company which is now a subsidary of Zeiss. Zeiss binocular and riflescope production largely from Hensoldt ag in Wetzlar. I think you will find that this scope was imported somewhere around 1953. Hensoldt was last cataloged in the US in 1968. I have had some dealings with a 8x that was valued at $200-$300
