Just thought I'd post this for info:
After a few brews where I'd had problems with final volumes of beer not being as expected, I decided to check out the calibration of the volume markings on my FV.
I brought home some measuring cylinders from work to do it accurately, and found the Young's FV markings were 2L higher than the actual volume. See photo.
Not sure if they vary form FV to FV depending on where the markings are printed, but the 23L mark seems to be the bottom of the upper ridge.
