Some years ago I remember writing somewhere about the vexed question of the V12-engined Briggs Cunningham Maserati Tipo 63 which Walt Hansgen had crashed at Tertre Rouge, Le Mans, during that year's 24-Hour race.
In course of 'repair' by Maserati back in Modena its mechanical components were actually transferred to a replacement chassis frame, then shipped back to Cunningham/Momo in the US under the original entity's chassis number.
Years later the set aside original chassis - whose short wheelbase had made it too nervous to be wanted back by Cunningham - was acquired from Maserati by a marque enthusiast, and it passed subsequently into other hands - all under its original chassis number...which was duplicated on the later-season LWB replacement which also survived.
Thus we had two Tipo 63s in differing configurations but both with claim to the identical original chassis ID - one having been 'the car' dating from early 1961 up to Le Mans, and the other being 'the car' as run during the latter part of that same season.
I recall writing about the matter and it being published somewhere, but for the life of me I cannot now locate where. So this isn't exactly a missing person plea, more a missing feature story plea ... if anybody sees it, or recalls it, I would really appreciate being given a lead on where to look.
