Hi Folks,
Just to present my own wee observations...the pommel form is very unusual, not what you would expect to see on an original C16th sword (but not so difficult to manufacture with an C18th or C19th metal lathe
)
The grip has a top ring which meets the pommel base, and the grip top diameter is less than the pommel base diameter, where pommels stretching towards the grip invariably meet the grip flush for smoother handling.
The quillions appear to be too thin to be practical for this sword type.
The blade type is unusual for a two handed sword of C16th style. It would not be usual for central fullering to run for the full length of the blade, as a two handed sword blade of this type (long and with a very shallow width taper) should have a good distal taper, which should preclude the need for central fullering after about half the blade length.
This would suggest that this piece would not handle too lightly in the hands and cast a questionable shadow over its practicality.
The blade form (shallow width taper, central triple fullering) and makers mark is identical to a single handed blade that I bought some years ago and hilted as a German Katzbalger. This was a C19th blade made to an earlier style.
I would suggest that this sword is an example of the same.
As a C19th repro of this quality (not bad but not top), I would not suggest that it is too valuable. £150 - £200 tops maybe?
Hope that helps and all the best,
Macdonald
