L48 MV block on eBay

[Petes L48]

Spotted this one on eBay when looking for orphans.  Any thoughts from the experts on the missing partial VIN?  Looks like the top deck was lightly machined.  Is it a re-stamped engine code, or maybe just the partial VIN was removed for someone looking to re-stamp their own VIN, or possibly the VIN wasn't stamped as deep as the assembly code?
