Leupold M4 & Ultra M3 10X40 serial# & dial direction:
Leupold changed the direction that their dials turned.
Many may already know this information as I had but I was going to buy a MK4 M3 in the FS section the other day and it took me a while to locate this information so here it is (FYI, it was written in 2002):

If you use a M3LR scope and are ordering new turrets from Leupold, make a note of the serial number. There are two different runs of scopes. Some have F in the serial number and the newer productions have a G. The important thing to know about the different lettered scopes is that the turrets run in opposite direction of each other. You'd hate to get your nice new turrets caps and find that they are marked backward.</span></div></div>
It looks like all Scopes made from the "G" suffix 1999 on elevate counter clockwise if sitting behind the gun. While older scopes like mine with "F" and prior suffix elevate clockwise.
older up to "F" suffix dials: ...1...2...3...4...5..6...7...8...9..10
newer "G" plus suffix 1999 and on dials: 10...9...8...7...6...5...4...3...2...1...

9. When was my scope manufactured?

Scopes using a letter as a prefix (the beginning of the serial number) were produced between 1974 and 1992. Scopes using a letter as a suffix (the end of the serial number) have been produced after 1992. On the chart below, you will notice the letters “I,” “O,” and “Q” have been omitted as they are easily mistaken for “1,” “0,” and “0” respectively.
