I too have a few Mantons and when I saw this thread I tried to locate copies. I searched a lot of places and found only two listings for the original book. They were priced around $300. I found 8 or 10 copies of the supplement; all priced at around $70. I finally found a set of the two on eBay in good but used condition for $200 for the pair. They are interesting books. One thing that jumped out in flipping through the original was a set of photos of the original case labels in B&W. They are high quality photos of a size that could be photographed and used for making a really good reproduction label. They may have already been used for this.

I noticed that the original of the book was published in 1966. I noted that Joseph was born in 1766. I wondered if this was by accident or by design.

As mentioned, then books I found were pre-owned. There were two personal library tags on the front piece, but the interesting mark was a penciled label at the top of the inner front dustcover (which is in a protector). It is labelled "Gun" with an underlined and below it the inscription "Dan Manton & Son LTD". Anyone have and idea what the connection might be?
