An example of what I believe to be a fake Woodward slider taken (if memory serves) from a Rydal School OTC badge:
Fake Woodward Slider.jpg
Whilst the font used on the fake slider (uppermost) is reasonably close to the genuine font, the differences are apparent. The font stamped into the genuine slider (lowermost) is thicker and spaced much more liberally, being nowhere near as crowded as that on the fake slider. Note, also, the differences between the apostrophes in 'B'HAM', and the spacing between the 'F' and the 'E' on both examples.
And perhaps most obvious of all are the differences in shape and length.
