It was cleaned up quite a lot Dan, it was purchased from ebay with big rust patches on the blade, Tatyana cleaned & etched it with phosferric acid.
She had a great result, no pitting & a laminated blade to go with the handle & overall lines.
She normaly finds great swords of whatever design, I understand she veiws them as art pieces to use for intierior deisgn at her home. Shes certanly got a good eye for pieces that stand out.
How many made? I have no idea, but I think there a lot more of them about than even most seasoned collectors realise. The laminations are not usualy visible at first though due to cleaning,polishing, buffing,sanding over the years & perhjaps some were not ever etched even when new.
I wouldnt say there common, but they are about.
