Hi Glen,
thanks for the reply ...here is a better picture of the pommel. To me it looks like a nut but the tang could have been peened over the finial (after passing through it) and due to the fact they are both steel could, with the effect of age/rust etc become almost invisible ?
Another picture provided by Marc on SFI
....unfortunately no details other than the sword was sold via "Le Hussard"
Best Regards David
