Thanks to all for your advice and assistance.
Yes, about what was expected based on the pics (the top of the wrench flat is quite close to the rivet). Some change must have been made, possibly to the 'cup' or the rivet for the spoke reinforcement. Or their measurement was just to the rim without taking into account the 2-3mm that the spokes protrudes into the nipple.
If you decide to not respoke the front, back off the tension a bit. The front can usually withstand lower tension since it has no dish. In the short term, brass nipples shouldn't fail even of not penetrated to the head.
