It's a pale roast malt (like Chocolate/Patent/Roast Barley), you can make some yourself in the oven from pale malt if you want, the oz.craftbrewer page says ( http://oz.craftbrewer.org/Library/Methods/.../roasting.shtml )
150 to 170c up to an hour (depends on type of flavour desired) - roasted in the oven.
Closest flavour substitute would probably be something like Weyermann Cara-Aroma, or Chocolate malt.
