For some reason - I can't quite put my finger on it - I don't think this one is real.
My dad used to build tanks. It's possibly what killed him (the materials that were used - his doc said it's likely what caused his cancer, and indeed it's the same cancer that killed my granddad, who worked with him -- my mum's dad, not my dad's dad).
I got to ferret around inside a tank on an open day one year. Felt like Maggie, I did.
He worked at Chilwell Depot. It was a shell factory before it built tanks. Apparently every other shell that was fired during WWI was made there.
