The 'A1273' is almost certainly an A1278 marking that's gotten scraped a little bit. Those markings are silkscreened on, and they don't stand up to much punishment.

If you look at your MagSafe power adapter, you'll see a marking that indicates the wattage; those disappear if you look at them crosseyed. When those power adapters get into the used market, it leads to people plugging their Macbook Pros into underpowered chargers that will power the computer, but not charge the battery. ''sigh''...
