I'm sorry I'm a little confused, this thread is a year and a half old and I don't get if you managed to find any wallet or key
Based on this I guessed not
Found 70 possible wallets
found 0 possible encrypted keys
found 0 possible unencrypted keys
The 70 only means pywallet found 70 master keys but no addresses at all, this means weird
When were the wallets created? Are you sure it is a bitcoin-qt/core wallet?
BTW I found out the pywallet recovery is bugged, I fix a bit of that a couple hours ago you can try the new version and see if it finds any key
