Thanks for the review Gray, nice to see how the kit breaks down.
I didn't see any discussion about historical issues with the kit here but the mail byrnie is fine as far as I can tell from photos of the painted model. The clothing is fine (does the painting info say anything about the wickelbander?) but there are too areas of possible inaccuracy - the helmet and shield.
The lack of rivets around the rim of the helmet is easy to remedy if one chooses to but the shield will be a trickier fix since the hand appears to be cast in situ. Ignoring its thickness (dictated by casting considerations) the varied-width boards on the shield are notably good but the 'edge clamps' are questionable. Your pic highlights the major problem with it though - the boss; it looks far too large. But since it is largely hidden from view this probably won't be a major concern for most of us.
