Further to my last, I have just heard from my collector friend (the one who does medal mounting, whom some of you will already know) and he tells me he has a group of four with the 1914 Star and bar to a chap who had served in the Army Service Corps, been discharged and then joined the Merchant Navy. Definitely a scarce combination.
As you say, L-B - not campaign medals in the strict sense of the word, but generally described as such.
