Ward & It7010: Thanks for the input.
I have no idea when they were made but I just did a search on the internet and apparently the Hertel & Reuss Company went out of business in 1995!
They were bought out by another company but the name ceased then.
Lots of good comments on them optics wise but no other useful (repairs) information found as yet.
I took them out again this morning and observed Canada Geese, Antelope, Whitetail Deer and Mule Deer with them.
No eyestrain as yet.
Thanks again
Hold into the wind
