Hello Sionnachdubh,
I'm sorry I can't help you in your quest. My reason for the reply though is my great interest in Scottish weapons and I'm always on the look out for makers of such. I just got back from checking out their site, which is great by the way, and saw no mention of weapons for sale. Where can one find this information out? Do they in fact make them or do they have a specific source that provides them with all their needs? I'm a fan of Mike McRae from Scotia Metalwork www.scotiametalwork.com and Vince Evans www.arscives.com/vevans/( I could go on) and it would be great to find another similiar source. Any help would be greatly appreciated. I did try to search for the info you seek via various search engines and I couldn't find anything other than the website for The Wild Highlanders.
Yours Aye,
Sean
