I have an original "Best Way" & "Not" here to compare.
My original AC "Best Way" square mesh came from a box without a date on it & no hot melt stamp either.
It too has the wire end overlap inside & out,and a recessed valley groove on both sides,but it's up against the inner circumference,not the the outer like Marks is.
The "Not" I have is a post 74 Diamond mesh with almost the exact same characteristics as the "Best Way" above.
