Something fishy about this Sauce

Worcestershire's got sauce. Lots of it, mostly in a display cabinet at the Worcester City Art Gallery & Museum, which I visited during my recent stay in Birmingham. I like esoteric little exhibits like this.

The 'Original and genuine Lea & Perrins sauce' was first manufactured in 1838 in Worcester, after a recipe was brought home by someone from the East India Company, who'd discovered the sauce, or something similar, in Bengal. Or so says Wikipedia: http://en.wikipedia.org/wiki/Worcestershire_sauce   (What would we do without Wikipedia? I might even donate something to it. It's not a multibillion dollar company, like it could be. It's a charity, basically.) Later they moved production to Birmingham, where it is still made to this day. Lea & Perrins was later owned by HP Foods, the Imperial Tobacco Co, and now by Heinz. The sauce's ingredients include tamarind, molasses and anchovies, so it's essentially an Indian fish sauce.

 What else do you see in Worcester Museum? You see a very big fish that once swam up the River Severn, you see a rather nice cafe, you see a display about the Worcestershire Regiment, and down the road, on the banks of the flooded River Severn, lots and lots of swans.
