You can translate this back to Script by hand using either that [Bitcoin Wiki Script page](https://en.bitcoin.it/wiki/Script) or else the handy tool at [Chain Query](https://chainquery.com/bitcoin-api/decodescript). Just look at one byte (two hex characters) of data at a time, unless you're told to look at more by an OP_PUSHDATA command (0x01 to 0x4e).

If you'd like a mechanical hand with this sort of translation in the future, take a look at the online [Chain Query](https://chainquery.com/bitcoin-api/decodescript), which translates from hexcode to opcode, or the Python [Transaction Script Compiler](https://github.com/Kefkius/txsc), which translates back and forth.
