A difficult badge to judge in my opinion.
Just like all single metal construction items one has to rely heavily on general indicators such as slider shape, general finish and patina as well as examining the known fakes.
I have no reliable indicators for this badge.
If you look at the obvious fakes sold by the likes of the British Badge company you notice they produce a sample in brass with the flag pole not connected to the upper scroll. Also to note that the scroll ends are joined to the turrets with a "butt joint" rather than a singe point.

This "butt joint" is not an exclusive indicator of a fake as I have seen many samples that I consider good with it.
The example I have has the "point type" joint between the scroll and turret and unusually has a WM slider. My badge is very similiar to Paddy's - but has some extra wear to the title scroll. Having had a quick look at the images posted they appear to me at first analysis that they might be from the same die, with possibly some extra voiding done to the scroll attachment in mine and Paddys.
I believe it to be genuine - but have no proof positive.
comments welcome.
