Melody reminded us that we all have collections of our own, and Catherine that it could include matchboxes. I have a matchbox cover from HMS Barham, a 1910 British battleship, with the initials of my grandfather F.P.Busbridge engraved on it from the time he served on it in WWI.

My father also served in the Barham in the Mediterranean in 1937, just prior to WWII

Fortunately, the navy transferred him to another vessel before the Barham met its fate in 1941, but he lost a lot of his friends
