Beginning around 1970, some manufacturers include a number printed on the playfield behind the play tray door. This number can help you identify the year of manufacture. Unfortunately, the number is sometimes partially or fully obstructed or faded.
Below is a table listing the playfield number and/or description with the year of manufacture. Here are some pictures to show you where you can locate the number.
Here are some manufacturer specific notes:
- If Nishijin and the number starts with 47, 48, 49, 50, 51, 52 or 53 then add 1925 to the number to get the year. For example: 53 + 1925 = the year 1978.
- If Sanyo and the number starts with 4S then the year is 1974, if 5S then the year is 1975 and if 6S then the year is 1976.
