There were two MacBooks released in 2007, the mid year model could run 10.4.6 but the late year model required 10.5.
Is it possible you have the wrong discs? Are these the grey discs?

They are grey disks (2z691-6089-a and 6113-a)). I checked on the serial number, its suggests the original OS is 10.4.6.
This is the only machine I bought at this time (there is a chance I could have mixed it with a work computer - but seems really unlikely).
