Grey's article (that Grantwhy quoted) pretty much had the right of it.
We know he had at least two medium lasers, two ER PPCs (one mounted in the left arm, after the first fight with Searcy), an LB-10X autocannon, an SRM-4, and it's specifically noted he traded away his Gauss rifle for "Luxor" jump jets, which were custom installed by the "great Lazlo Falcher."
We don't have any more details about exactly what else his Banshee had or didn't, and there isn't a Record Sheet to date, but it should be fairly easy to approximate.
