By old I mean 1890s. It's a William Hume (Edinburgh) India model. I've just asked the National Media Museum (Bradford, UK) whether they would like it, but I suspect they won't (the National Museum of Scotland didn't).
If the museum doesn't want it, does anyone have any advice on what to do with it. As it was my great-grandfather's I don't just want to put it to the mercy of fleabay.
