Two serial numbers on the engine.

The number stamped in the metal just forward of the fuel torus reads "S/N 0000325".

Another number, "S/N 0000319", is scratched in the fuel torus itself. There is additional text scratched in the fuel torus, including some which is apparently crossed out, but some of the characters are illegible.
