No clue really. It was from a local auction. Nothing is visibly wrong with it. I can knock out the primers to make sure they don't just fall out if you're interested. If the buyer isn't satisfied, I'll refund their money. We would both be out shipping one way. (Small flat rate)
If you're just wanting to pass the test, it's really not to difficult. The air charts are the trickest thing. It's been 6 years since it took the in person test, but I just watched YouTube videos for a couple hours a day for 3-4 days and took it. The rules have evolved some since then though.
