Earliest memory of your first large win?

Hi

I have been hunting for the name of the machine i got my first large win on at around the age of 9years old.

I used to go to a caravan site in North wales where the arcade used to be fantastic in the 90s.

The machine had a top feature which went across the top of the upper glass where it was £4 spin £4 spin £4 spin £4 spin £4 spin it went left to right and after the first £4 it ended but this one time it went to £32 which to me back then was a huge amount 

Does anyone have an idea on what the machine was called?
