Thanks. I'm not sure it's an OCR B font
No, but that might be as close as you are going to get. I've only ever seen this font used on numbering machines. The six and zero are very distinctive in that the vertical part is completely straight, and the eight is also distinctive the way the top loop appears to be the same size as the bottom one. You almost never get that in a font. The only time I've ever seen this used is for numbering, and even at that it seems to be a particularly continental European thing.
