Does it have a brass ring and the nonocoating?
When lens filter threads were metal and metal-on-metal could result in binding brass filter threads were important. Nowadays most lenses have plastic filter threads and brass is not as indispensable as it was once.

I use a lens hood for protection and it does not ever negatively affect image quality.
Sure, but hoods do nothing for horizontal projectiles. However, I cannot think of many situations when a hood plus the standard B+W glass filters are not enough. Maybe the military could use them.

I had a bunch of them recently. Damned 35-40kt winds with sand and debris, followed by ice storms at about 75-80° angle. The ice was accumulating on the inside of the hood. Fortunately I was able to use the Lenscoat Raincoat to keep the rest of the lens/body from being blasted, but I can't say the same for my poor face.

I was at the Michigan City IN lighthouse when superstorm Sandy hit the east coast. Winds were coming down full fetch of the lake and waves were p;ushing 15 feet and more. Trust me. I had a UV filter on my lens. I had sand in my sholes, embedded in my socks and my tennies were sandblasted white again.

That is correct; however, the particular 1986 that you cite has not yet occurred.
Is anyone able to comment on the actual water repellency of these filters? I'm hoping for a way to keep raindrops out of my photos without having to hover about with a rocket blower.
