But the evolution of this Radio
Product from : SW1 SW2 SW8 GS800M Eton E1 is a
generally accepted fact.

Not fact.

The SW8 preceded the SW1 (which, with the addition of selectable
sideband synchronous detection, became the SW2) by two years. The SW1
and 2 constituted Drake's budget line. But your central observation
that the E1 is a knock-on from the 800 and the 2nd version of the SW8
is my understanding as well. The three are to my mind repackagings of
the same core receiver, varying in quality of execution and the
quantity of air included for the purchase price. The E1 adds welcome
memory capabilities, superior display, and pbs.
