Tam Again!Had to let you know.I've just found a series of photos taken from an RAF plane of HMS Wishart attacking and destroying the U boat - I think that was in 1941! There's a couple of really good photos of her.
Also the photo in the info. link I sent previously is not Wishart, but a sister ship.I found a site that has a glossy photo of Wishart for sale though. I'll email the page link once I have your email address - very long address! Sheila
