It looks like a really nice book. Has some serial number tables in the back. The serial number of your gun is close to Denys Finch-Hatton's celebrated .475, built 1911.

Since this guy was killed two years after he got this rifle, that might explain what looks like pretty high condition. It's certainly gorgeous in the book picture.

Ypres was one of the bloodiest names of WWI. Since the town remained in the salient for much of the war, several battles were fought there.
