Thank you for pointing us in the right direction, think we have the wrong medal card  

  Identifying the cap badge as Suffolk Regiment and again speaking to an elderly relative who now says her father may have been in a "London Regiment" during the war!  
The medal card for William Stroud 38626 Suffolk Regiment, on close scrutiny, has in the same box as the word medal "
Wm. C" directly under name William! As well as the Victory and British Medal this William Stroud was awarded the Silver War 
Medal Badge which I just happen to have in my hand  

At least with your help we won't be on a wild goose chase at the NA.
Regards
Susan
