Vin/chassis plate stamping

For the CSP311 project, I have a reproduction chassis/VIN tag, and I am looking for the number stamps/punch to put the chassis number back on (the same as on a S30). Yes, any stamp may well do, but I am trying to keep the car very much period/correct, so looking for the correct size and font Nissan would have used back in the day. (Plus I am getting very much OCD about the project!)

I have had a search here, I can't see anything (though it doesn't mean there isn't) and the 311s.org forum says the Habour Freight stamp is close, but not on the 4, 7 and 3, which doesn't help.

Any direction here please.

Cheers

Ian
