I believe up until the early 2000's they had dip stick tubes. The cover has a red lock tab that is broken to unlock it and replaced every time you need to check the fluid.
See, dip stick tube included.
11 Euros for the tool is nice, they go for about $16-20 on ebay here for the knock off version or $80 for the official version from Samstagsales.com
