Please look at all the photos for condition. Hayley or Bob Hayley recently passed away and we all lost probably the single greatest living source on reloading and manufacturing data on hard-to-find and obsolete ammunition. He is best known for patenting the Hayley Manstopper bullets.
About the only place, you will find mention of him is on reloading forums (I could not even locate an obituary to mark his passing). There is a good article in a 2012 reloading magazine, and I will be happy to send a PDF to anyone who requests it. 2021, I bought around 150 of the die sets or about half his collection. I will be listing a couple hundred items from his estate this week and items that are not allowed here will be listed on Gunbroker (Keyword Hayley).The item "Bob Hayley's Estate rare book 1914 British Sports and Sportsmen Big Game" is in sale since Tuesday, April 20, 2021.
