So far I am finding there seems to be quite a bit of confusing information on this model & year.
The serial number sequence apparently changed in late 1962, the round cyclops hood medallion disappeared, etc.
Mine is a 20301 model
Early: 2000 series SN, up to late 1962 (found with 01 series) :
1961 Serial number 131427 - 155530
1962 Serial number 155531 - up
Late: 2000 series SN, late 1962 up (found with 2000 series):
1962 Serial number 1001 - 11947
1963 Serial number 11948 - 38930
1964 Serial number 38931 - up
I'm finding parts, including the front bolster, claiming to fit Jubilee, NAA, 600, 601, 800, 801, and early 2000 4000 models.
I bought an early Ford because of the relative consistency of design and parts availability. I'm somewhat surprised by the variable information I am finding on my particular model & year.
I hope to sort it all out sometime soon. Thanks for your help!
