Sorry, but that 602 didn't come originally from Colt like that. It was modified later.
Burst and a 4 position selector didn't come around until a little later with the 605B.

Now, that's just not true.
The burst fire kit patent was filed in 64, at the tail end of Model 02 production. Most of the tool room prototype guns Colt built for the CAR-15 family (605, 606, 607, etc.) were built on Model 02 receivers, like the 16 in mid-length carbine for example, and most of them had burst kits installed. More importantly, the rifle in question uses the term "2 shot" which is the same nomenclature that appears on said prototypes. 2 shot was the earliest version of the burst kit and seemes to have been favored by Colt at the time, even though they also produced a 3 shot cam to go with the kit. All of this stuff was in development and was featured in marketing brochures in late '64 and early '65. 1964 also marks the transitional period between the Model 02 and the 603/604.
To say, with all of those things going on, that Colt couldn't have made a Model 02 with factory burst, is just wrong.
Now, whether they actually did or not, is a different matter.
I, however, am leaning toward it being original.
