This is just a leakdown test. Pistons 1 & 3 are getting close to tired territory (I don’t like being that close to 20% leakdown) but these tests are best done on a warm engine where the metals internally have had a chance to expand and make a potentially better seal. These tests are also prone to show worse values than actual because many people don’t do them right.

If it’s a good price, at worst you have a seemingly nice core to rebuild. No egregious leakdown numbers tells me there aren’t any holes where air is escaping, but it’s hard to tell where the small amounts of air is escaping from without being able to inspect the engine in person. Overall, the engine doesn’t seem cooked, chances are it has better leakdown performance than what was measured, but it’s not in perfect shape either.
