Hi theFeck.........welcome to TFF.
The Blue Book lists a whole bunch of different Series and Grades of Husky rifles. I don't find any listed in 7mm Remington Magnum.
Since you bought it in 1966, that eliminates some of the later models.
Best I can do is to give you a Blue Book price range for models made in the 1966 timeframe or earlier....
98% - $480 to $550
95% - $440 to $495
90% - $360 to $415
The scope would add a little to the value, but I don't know how much.
Hope this helps.....
