The Cambridge Saddle Brown Calfskin came into my attention a few years back when a Wide Margin Cameo version was sold for more than USD600 on eBay! Ever since I have been on a look-out for one too...no, not the Wide Margin version, but just a "regular" Cameo :)
And recently I was able to get one on eBay. And I must say it is lovely. The Calfskin basically looks the same as a Water Buffalo grained Calfskin only much more supple...which is a great bonus.
Now what I need is a Sea Green or Forest Green Cameo to add onto my collection... Or an UltraMarine Blue... ;)
