Hi Mike, the F114 is sometimes seen with 2/1, but it is less obvious than on the F111. On Gouby Page 79, his 1882Ma, he says "The only part of the 1 that can be seen, on this example, is the small portion that sticks, centrally, half way up the 2"
On more than one occasion I have also seen a tiny additional protrusion to the top left hand side of the numeral 2, which I think is most likely the top left corner of the top bar of the underneath numeral 1. I feel that this may be an even better indicator of this variety than the protrusion on the inner curve.....which always seems to be weak to the point of doubting the variety. When one considers the combination of these two tiny protrusions I think that gives increased confidence in confirming type. Here is a picture of my own specimen for illustration
