Thanks for ref. Found that one thing mine needs is the hook that goes on the buckle...not what I called an "A" catch above. Don't know diddly about helmets but saw this one at an antique bike show today at Denton NC for $35 and could tell it was real and not repro. Need to find someone I can send pics to for more precise ident since I can't figure how to post them here. If anyone is willing to take a look, PM me with an email addee and I'll send some pics. Haven't quite figured how to get the liner hooks off the swivels so I can take a better look at the two parts.
