Interesting document.
In sheet 11 of CS’s letter (dated “Sept. 11, 1962”) it's stated that “We certify that in excess of 100 cars identical with the basic specification stated in this application were completed on Oct. 1, 1962”
Looking in the Cobra Registry, Cobra CSX2019 was the highest numbered car in the shipment that unloaded in LA on 1st October 1962
There was some critical comment back in the '60s about Enzo Ferrari over-estimating the production numbers of 250GTOs (and other sports/racing Ferraris). It would seem that CS had similar myopia...
Cheers!
