Here is a close up of a second helmet rim inner section, slightly different construction but this looks like it fitted inside the outer rim. Found lower down the Malfosse adjacent to the lower battlefield in silt – anaerobic black when taken out.
Good Saturday dig in the malfosse immediately adjacent to lower battlefield. Another helmet rim. Different construction. This one – very interesting because it has an inner rim still in existence which is much more fragile than you would expect. I will post the images. This first one shows both the outter rim very similatr to the previous one but without the rivets on the sides. Slightly smaller diameter but when we took it out (Mark dug it out of the side of the stream in grey/blue anaerobic silt) it was found to have an inner edge which may have been the original helmet edge stuck to the bottom inside. When I washed it in the water the inner rim came loose as it was broken at one point.
Looking closely the bottom edge is folded and pretty much perfectly formed. It looks too clean to be iron. I will be going up to the Wallace Collection soon with the other rim and will take this as well. http://www.secretsofthenormaninvasion.com/imagemapfinds/battlefieldfinds/20saxonhelmetrim.jpg
