These items are probably American ). A lot of carved bakelite jewellery/buttons/buckles were manufactured in the U.S.A. The orange (red?) one is especially reminiscent of American bakelite, due to its polished look. The other one is probably butterscotch bakelite. Originally it would have been white or cream, but the plastic oxidises over time and changes colour to a butterscotch colour. The rectangular one is probably a belt slide. Some types of belts don't have any holes in them. The belt is just slid through the clasp. There is no notch in the centre bar indicating that there was never a hasp.
