Hi Ian,
had this magazine long time ago and still remember it.
The guy did not correct any faults of the Aurora kit, that would require an almost total scratchbuilt.
He just added a number of details, sanded away the embossed markings and gave it a nice paint joband hey, it looked quite convincing!
If you want to have an (almost) accurate Go.V go for the Hippo kit.
The article in FSM is not worth paying a high price, just my 2 cents.
If you need references of the full size machine let me know.
Cheers Joachim
