I visited the Chambre Hardman house a few years ago, shortly after it opened to the public - it's an amazing place, really worth a look. However, when I bought a copy of that brilliant Birth of the Ark Royal picture at the nearby National Trust shop, I noticed that the accompanying leaflet referred to shipbuilding in Liverpool, not Birkenhead.
This was an absolute travesty and I contacted the National Trust (which runs the house) to point out the mistake and asked them to correct it. I don't know if they have since altered their literature, but I suspect not.
This is perhaps where the Mail obtained its wrong information. To say 'Liverpool was a major shipbuilding centre for 200 years' is a bit wide of the mark. Many ships were built on the Liverpool banks of the Mersey, but it was the Laird
shipyard in Birkenhead that became famous worldwide.
The trouble is, it's easier for lazy journalists to say Liverpool because that's the place most people know. A couple of years ago, when Tony Robinson did his Time Team TV programme about the last resting place of the Great Eastern, he blithely placed it in Liverpool and not New Ferry, even though they were showing road signs saying New Ferry.
And, of course, the world-famous Mersey ferries are all to do with Liverpool, aren't they? Who cares that they stem from Birkenhead? In 1330, Edward III granted the monks of Birkenhead Priory the right of ferry for ever.
I could go on, but you get the point.
