Yes!!!
At last, my search is over. I have in my possesion a machete, about 22" total length. My father found it in the woods in the early 70's when working at a powerplant in northern Sweden. It has since then been lying under the sink in the kitchen, until I decided to finish it up. I polished away the rust and replaced the handle. In an almost illegible text you can distinguish the text: "Martindale Birmingham England No 23W", and a "frog-like" picture.
Well, now I know some of its origin. The question now is exactly how old it is.
Thank you for the link and the info.
