HZ & HX Sandman and Engines date codes

[playwme]

NT prefix I think is the Nasco replacement block numbers that are used in the case of warranty. From a collectable point of view they're the next best thing to the exact engine number it came from the factory with.
HZ looks good though. That date code would be good enough for me if I was buying it. I'd even consider the HX ok with the police number (although I'm not as fussy as some). Cops do funny stuff sometimes. They gave me a police number for my engine cause they couldn't find the number, lucky it wasn't the original block for the car.

Thanks Mate that makes sense. Cheers
