Is "The Iron Time" worth the money? I don't have a copy and haven't had a chance to view the book. BTW, super EK... how many do you have now? I saw your display in another thread and it looks as though you could use a few more. I need to find a few more examples for my tunics... real, but simple pin back types. In over 20+ years of collecting I have never convinced myself to buy a screwback. I have no idea why as I love the EKI. I only have around 10 now for display and tunics. I sold many because I thought I had too many. What the H*** was I thinking!
