Thanks! I'm not the most computer savvy guy! I got some pics but I'm having trouble getting them from my phone to my computer! The numbers I posted earlier are the only numbers on the block and they are on the front. No numbers what so ever on the sides of the block. There is an A2 on the front of the block also top middle. Pics won't send from my phone to email. Something wrong with email on my phone. Have to get one of my kids to figure it out! lol
