LHD Cortina mk1 was the VIN number stamped anywhere on the chassis?

[Dinoplex 3]

Hello, a friend of mine has a 1966 lhd cortina mk1 with 1.2 engine. The car failed belgian inspection because "they couldnt find the vin number as a stamping on the chassis". Did Ford really not stamp any on the chassis? There is a plate with VIN number on it but the belgian inspection people for some reason are so fixated about the VIN to be also stamped on the chassis itself. He also said this below

"Haynes claims there's a VIN plate after Jan 1965 but it doesn't say if it replaces the VIN stamping around the strut tower and it seems like the Antwerp importer just slapped on an additional tag with the VIN on there instead of having the strut area stamping"

Would ford help him with stamping the VIN number somewhere on the chassis? Apperantly it needs to be "stamped by an official entity" which is ford themselves.
