The bar is shown upside-down as the MM would be shown to the left of the other medals as we look at it. (The MM and the 1914 star are correctly shown in the portrait you posted earlier).
The ribbons are well worn and faded but, in the correct order, appear to be :
Military Medal
1914 Star
Victory Medal
War Medal
The first and last ribbons are in good condition and easy to identify. The '14 Star is well worn but has the rosette, which was added in 1919. The really faded/washed one must therefore be the Victory Medal, though how it ended up looking like that is anybody's guess !!
This set concurs with the Medal Card held at the National Archive.
(BTW there is a note on the Medal Card referring to the issue of 1914 Star but I didn't want to pay to view it (

so I'll leave that for you to read ! )
