It looks pukka to me.
It's a bit hard to see as the photos aren't exactly sharp but it looks like a dot display in the 1.11 picture. Also I think that I can make out a light sensor under the display and some digit drivers above it which would suggest that it's got the rarer early P2 module in it.
According to the first inflation calculator I came across in a google search: what cost $287 in 1972 would cost $1454.27 in 2007. So not exactly a give away either.
