On that Hunter's Lodge page there is an advert for "Zulu Nation" muskets.

Don Heath, now deceased, enquired to me several years ago who might be interested in purchasing and reselling a very large number of muskets, muzzle loaders, ML pistols etc, several hundreds in fact, in more or less pristine condition found sotored in I think it was Zimbabwe (?).

I wonder if these "Zulu Nation" muskets are from that old stache.
