This Jaguar XKE Series I 4.2L LHD OTS car does not have a 1E prefix on the factory build plate. Its car number is 10272.
Two or three other owners of the earliest 4.2L XKE's have reported that their cars lack the 1E prefix. It seems that the 1st.
200 to 300 cars produced did not have the 1E prefix but only a five number car number on the build plate.
