Take note that the wallet.dat file should be an intact-unloaded backup or newly created by those old versions.
An old backup that was loaded to some newer version could had been upgraded to that version's format.
(although nothing much have changed on an old/new legacy wallet's "magic numbers" appended to the private keys)

If you failed to get one, you can create it yourself:
Download the source from bitcoin core's github repo old archive here: https://github.com/bitcoin/bitcoin/tags?after=v0.2.11
Build it and create a wallet.
