Milbro

Somwhere 1950-1970, the Milbro was in production. It is a relatively small slingshot, especially the fork ends are very close to each other. It is made of polished metal, and has strong square elastic bands which are attached with a wooden wedge. It is held in hand with the thumb on the rough (in this case red-painted) part under the forks, and I think that the handle is too small to hold it in a different way. Usually, the slingshots came unpainted, but this one received a painting from the gunsmith, so the police could easily see who it came from, in case the boys were caught doing, well, all the things you are not supposed to do with a slingshot :-)
I believe Milbro was not an American, but a British manufacturer.
