Nope, that's volume 2 and 3 of HO 249. HO 229 has six volumes, each covering 15 degrees of latitude, e.g. 0-15, 15-30, etc.

One volume of HO229 is for latitudes 0-45 degrees and the other is for latitudes 46-90. If we were on a training mission where we knew that we would not be going north of 45, we only carried one. For operational missions (airborne alert), we carried both.
