Boy, that's a tough one. It's not a 0 because it's not high enough. It's not a 2 because the leg at the bottom isn't flat. It's not a 3 or a 5 because it's closed in on the left. I don't think it's a 6 either (compared to the other 6). It MIGHT be an 8??? If it is, it's either 124379N567287 or 124679N567287
