Hensoldt nowadays is Zeiss military product line.
But sometimes before 1960-70 it was an own brand with civilian sales.
I have never heard of any civilian 10X scope from Hensoldt in the 60th so I assume you are going to buy a military snipingscope problably made in 1980th-90th.
They are good scopes and the Swedish military are using Hensoldt 10x42 for their sniping rifle and antimaterial rifles. (Accuracy international 7,62 and Barret light fifty)
Some of those are fitted with illuminated (tritium) reticles and some of them are not.
It might be a problem for you to replace the tritium when it's burnt out, as Hensoldt don't wanna touch it again.
Othervise it's a good scope, I don't know that the Swedish military have had any serous problems with them ( they had with their terrible Barret rifle but not the scope)
I do own one of those 10X scopes as well but I havent used it much as my use for a fixed 10X is limited.
