How good or bad are the B&L scopes that were made in Japan!?
I have 4 (6-24, 12-32, 36x)
There is a good reason the 6-24's command a pretty penny on Ebay
Amazing clarity, crisp focus even at 1200 yds
They have the red green and blue spectrums of light perfectly focused at your pupil

I don't know how scopes now can do what they do such as Arkens which are great for the money
But I must suspect it is due to CNC machining now and possibly coatings got cheaper than before
Coatings use rare elements so can be expensive
B&L's cannot be beat from what I've seen in a 1 inch tube and 40mm Obj. of Vintage scopes made back in their day.
---except by maybe a Unertl
a B&L can make a Leupold look like dirty water by comparison
Freda at Unertl said that ....Because of environmental laws they could no longer produce the glass with the same lead content and had to halt production.

B&L's
I'm told the glass used in the Balvars was rejects from aerospace programs in the 60's that would allow a camera to photograph a license plate from an SR 71 traveling at 3000 miles an hour at 70,000 feet.
---------------------------------------------------------------------------------------
The Balvar V8 and Balvar 24 were by far the most expensive scope in adjusted dollars commercially produced.
Reasons a Unertl is special is because he had a monopoly of some special local sand he used for the glass which produced unmatched quality glass until Enviro laws stopped their production
Plus he used to grind his own glass which if you watch how to on U tube, is a very intricate process
Supposedly a computer programmed machine cannot do it as good as a human can by feel and inspection)
Then of course, Scopes were low tech stuff for that company compared to what they really made money from
Per John Unertl:
"I’m not sure if any of you out there were aware we made very sophisticated optical/mechanical instrumentation, optics for military jet gunsights, fire control optics - (military stuff, not firemen) and wind tunnel instrumentation. Unertl Optical was far from operating out of a barn. We made the money with the high end optics, not making scopes, Scopes were more a labor of love as that's how the company was started and the funding for the scopes was a carry over from their high end contracts.

Dang I want that Big ass Unertl !!!
The B&L's are my favorite scope for 100 yd bench
and even have one on one of my 1000 yd guns, they are that good
