Hi Steve
I believe this is what you are looking for. What you have is the "dress ribbon" that has unravelled.
The ribbons are worn on less formal occasions. The medals are worn on Parades and are heavy.
The unravelled ribbon was bound around a former, which seems to have separated. When intact it looks like a small bar wrapped with the ribbon.
The medal itself must be else where.
When I was presented with my medals: Along with the main medal there is a miniature. Complete with ribbon.
Then there is also a ribbon bar.
I believe that the mini medal is a more recent award and was not awarded back in the 40's but that is guessing.
The image titled index shows what the bars look like, not related to the ribbons you have displayed.
Hope that helps

Cheers
Hopefully that helps
