Similar situation here. Just bought one of the last Mk 2 estates (used, first reg March '14) and no service book, just a print out showing
Date and location of PDI.
First service (entry is 7 July 2015)
Another service (entry 20 July 2015) - not sure why this is unless it was because it changed from extended to fixed service intervals....seems odd.
Skoda dealer even gave me the internal invoice for the service - £75 quid. I remarked that it was a fair markup from this to the ~150 quid they'd charge me to have it done and they admitted that I shouldn't have seen the pricing...!
The glossy paper folder the printout is in has the VIN code and a lot of other 3 digit codes stamped on it, though...maybe these are something to do with the build variant.
