That sucks, but I agree with everyone else. That is NOT tempered or PDI glass. Tempered glass breaks into thousands of tiny pieces, not dangerous shards like plate glass does.
Personally, I would never ship such a nicely restored game like that and rely on STI to wrap it. I've always crated them. I've been fairly lucky with stuff that has been shipped to be by STI, but I've also had my fair share of damage claims on items shipped via STI to me. Luckily, the shippers fully photo documented the pickup and their wrapping procedure which leaves a LOT to be desired. I've never had a claim denied yet.
Looks like a beautiful machine. Would love to see pictures of it pre-shipment.
