I've been a re enactor for years now and whilst at events up and down the country i have noticed that the polish in particular make some great stuff,stuff we (the people in the uk ) do not seem to be able to match in quality EXCEPT tents, swords, helms and some fighters . ;)
Ever since seeing the quality of their crafts i've kept an eye out for more on the net as well as whilst on events but, unfortunately i cannot read or write polish and as i work in bone antler and very little horn i have only picked up these words. I'll stick a couple of sites up as examples and would look forward to scanning through anything anyone else comes up with, it doesn't have to be polish and feel free to prove me wrong!

makes some interesting stuff, particulary lamellars look impressive.

Can't say anything about they accuracy, as lamellars in Europe are generally dubious stuff (at least for me ;) ), and those are mostly based on good old Birka found.

Still look great, as well as other items.

was one of the other ones i have and yes, lamellar is a tad tenuous but does look lovely stuff, yet again they do do good stuff!
