Futura Extra Bold is very close, two of my versions are very close but not exact. 2's and 5's are off.
You may want to try myfonts.com sometime. in a section called what the font. You upload your image (cleaner the better) and often it can pick out the font automatically. if not you can submit it to the what the font forum and experts give it a whirl.. usually pretty quick too.
