Sir Dennis,
Yep, before I went over to the gold patridge, I was using a black one
with the top rear corner filed to 45 degrees
and painted white on the 45-degree patch,
used automoblie touch-up white paint.
It came in a little bottle with a brush in the cap similar to fingernail polish which I did not have on hand,
Wife never used white.
That is what I had with the flat-top-square-notch-filed Wisner-copy African rear sight on the .500 A-Square.
Worked fine on nearly a ton of 5-1/2 y.o. bison at 50 yards.
On a rat gun that sight set works well for squirrels too, whether albino or those big black monsters in Canada.
