The site showed the revenue weight as 4250kgs which is also shown on my v5c in section Y and F.1 so it looks like the DVLA have missed it off your v5c. As for other authorities I have no idea!What weight did the records quote for your vehicle? In which section on your V5C does tat weight appear?
For my MH DVLA records only give 'Revenue Weight' which on a V5C is in section [Y] which does not exist in most other countries equivalent documents, and my Section [F.1 Max, Permissible Mass] is blank.
So where do the Austrian or any other authorities legally stand then?
