Thanx everyone. I have a print of the LG entry, could not find his name at the site given, seems to be very selective compared to original.
I have my GF's details - Captain D Bremner, Merchant Navy skipper.
According to one of my aunts, they were apparently the first out and the last back carrying ammunition. The actual citation and medal have long disappeared and nobody in the family now knows anything about this, but it is really to find out why Eyemouth was used and where they were taking the ammo. Sounds as if there was quite a few ships involved.
