Tell mit armbrust - Wilhelm Tell series of Switserland

probably continuing to show my ignorance of the Swiss defs.                   I had a look at my 10c. values and they all appear normal i.e. the horizontal bar in H is 'high' as shown in tobben's left hand stamp.            So I looked at the 15c. value  -  pix attached  -  the bar appears to be the 'low' version, or am I in need of Specsavers ??              As can be seen in one of my pix, there is a definite frame break at the base line, and this deep purple looks variable in colour, but then that may be due to washing/cleaning etc.     Sorry about the white hair caught in just the wrong place between H and E.
