Taxing my memory, the total was 1,132 + x(single digit).xxx... and immediately put in a freshly created InstaWallet bitcoin wallet. A couple/three days later I split the three accounts up into 1,000, 132, and x.xxx... wallets, always using InstaWallet while in my possession. Hope that helps with your plans.
