Small green dots at right 1/2d

Post by paulmappkgv »

Hello,

I have just reviewed this part booklet I purchased recently and noticed two small dots at right, corresponding with the top of the revenue bar. I wondered if anyone else has seen this before and know their significance.

Kind regards

Paul
