These "Question mark" like engravings appear on a lot of bats made during the 1920's and earlier. They appear on the bats that have the H&B center label. I've been trying to narrow down the years for some time. I checked a 1932 catalog and found no "Question Mark" like engravings on any H&B labels, so it is possible that these bats date before 1932. I have to look into it further. Other markings on the Cracker Jack bat could give a clue to the age such as any registered trade marks.
The sides with the same marks are equal.
The touch lines.
The sides with the calibration marks on it.
To show it just make ticks marks. Like one tick mark for all of the sides that are congruent to this measurement. Then two tick marks for all of the sides that are the next measurement and congruent.
If you look on the sides of the cams and the puleys that involve the timing belt you should see little white dots. that indicates the marks.
Just draw one! It can help if all the sides are different lengths. Draw three of the sides, making sure that the first and third sides are not parallel, then draw the fourth side, making sure it is not parallel with its opposite side.
no some shapes like the rhombus have 4 sides making it a quadrilateral but 2 of its sides are not parallel
The stripes of the lands and grooves will be on the sides of the bullet. If the bullet is "stripping" through the rifling of the gun, the striations (proper name for the rifling marks) will be smeared.

Equal sides in geometry are represented using a variety of symbols and notations. The most common symbol is an equal sign (=), which is used to show that two sides are of the same length. Another common notation is using double bars (||) to indicate parallel lines, where the sides between the lines are considered equal. Other notations can include marking the sides with tick marks or labeling them with the same letter.
