Some of his collection was sold though London Coin Auctions in 2009, Auction 124. I think lots 1135 > 1367. It's good to look through them for the info and a bonus having the images. He also had a sales list that he sold coins from.
Davies told me about the 2 different obverses, noted after his book was published. I bought a few specimens from him.
