1933? Dutch 1 gulden silver (zilverbon) certificate [solved]

I have 3 Netherlands 1 gulden zilverbon notes, 2 are 1938 and 1 is 1933? I cannot find a reference to the latter date. Maybe I am answering my own question but, could it be that the date stamp had insufficient ink on it to print the date fully or it maybe faded, also it has a cancellation stamp on the back of the note so I was wondering that it might have been a test run that got cancelled. Any help on this would be much appreciated.

To me it looks like an 8. How do the other dates look like?

Other dates are a lot clearer as the are a better quality note, I will just list it in my collection as a 1938 single letter serial and leave this post run for a while

I just want to know how the 8 looks, sometimes 3 and 8 have a different form which would eliminate the possibility.

The ragpaper is not making things too clear either, the more I look at it the more it does look like an 8. Just wishful thinking I guess

It is definitely 8! 

I had a look at it in Photoshop, enlargement enclosed. You can see the stroke on the numeral 8 is there in the upper date, but very thin. Also, the shape of the 8 is different to that of the 3 on both notes.

Thank you for the effort, very much appreciated. I guess I can put this one to bed as solved.
