This is how you read the date code and size on a rim. In the second picture of the black wheel example means:

M5/9 = motor wheel company made on 5th shift / in the year of 1969

next to valve stem 3 = march then valve stem then you'll see a 14, which means 14th day of March in 1969 the wheel was made, date code 3/14/69

after the 14 you will see a 5.5 which is the wheel width means 5 1/2 wide
