Really grateful for the quick response. I've edited userStyle.css to read (as there's no Bold Italic in my Garamond set, I've left this as Droid):

@font-face {
font-family: -ua-default;
font-weight: normal;
font-style: normal;
src: url(res:///Data/epub/FONT/garamond/GARA.ttf);
}

@font-face {
font-family: -ua-default;
font-weight: bold;
font-style: normal;
src: url(res:///Data/epub/FONT/garamond/GARABD.ttf);
}

@font-face {
font-family: -ua-default;
font-weight: normal;
font-style: italic;
src: url(res:///Data/epub/FONT/garamond/GARAIT.ttf);
}

@font-face {
font-family: -ua-default;
font-weight: bold;
font-style: italic;
src: url(res:///Data/epub/FONT/droid/DroidSerif-BoldItalic.ttf);
}

@font-face {
font-family: "sans-serif1";
src:url(res:///opt/sony/ebook/FONT/tt0003m_.ttf);
}

h1 {
font-family: sans-serif1, sans-serif;
}

My flashed Reader has the file structure as in the screen shot I attach. But I'm still getting the old Sony default font! I've tried this across a range of ePub books (mostly from Feedbooks) and have checked in Calibri that there's no local font over-ride... I have to say I feel a bit confused. If anyone can clarify where I've gone wrong I'd be really grateful. Very odd.
