Tom,
Great dagger and fabulous pictures as usual. There are a VERY limited number of these Horsters that have appeared with slant grips. The earlier and first production run featuring the WKC 1st crossguard are normally internally numbered with the latest figure being "45". A couple of the slant grip versions of the dagger shown above which followed are also numbered.
That number "14" V was a great catch and all three early configs from Horster are very scarce. As a matter of interest, the firm also used the WKC transitional prior to the more common last style Horster and after the type shown above.
In short, they used three crossguards ( 1 of their own ) probably in a 2 year period before settling on the the final and widely recognised Horster design.

Aqquiring three is just plain greedy smile.
