If you don't mind checking and are willing to send something empty over, that would be much appreciated.
You don't really need some empty old wallet.dat files from me or other people. With the links that ABCbits gave here, you might be able to get a Bitcoin-Qt or BitcoinGUI client from the era of your coins. You may need to do some digging here and there, I'm pretty sure you'll find some helpful Bitcoin software archivars.
You can then generate your own empty wallets with random keys, encrypted and unencrypted, whatever suits your needs. Good luck.
If it's not obvious for you: never do data recovery without having redundant backups of the original media. Only work on copies, no matter what. The original media backups shall always be mounted read-only to avoid any possible writing on them that could cause any further damage to the content.
If I have to recover some serious value, I'd make forensic bit-by-bit image copies of the original. If possible check the identity with crypto checksums. The original is then not touched anymore. From the forensic copy, I make another copy. This last copy is then the source copy for recovery destination copies. Goal is to touch the original as little as possible and never loose a redundant forensic copy of the original from which as many working copies for recovery can be spawned.
