Thanks. I have it down now as a G1v2.Following what @BBS-1 did with his series "for dummies2 I'm leaning to differentiate the various versions (v.1, v.2, v.3) by the slight differences of the heads (markings, springs, ferrules, guards) rather than by the color of the handles.
The Turquoise (supposedly marketing for women) and the "66" are somehow special editions and their nomenclature as G5 and G4 is too well established in the shaving community to be changed. As far as the blue handle with the regular gold-plated head (the chrome "66" is rather the exception) maybe it should be cataloged among the various G1 versions depending on the slight differences between v.1, v.2 and v3.
Basically I would stick with Blue handle G1 or, too be
pickymeticulous, Blue Handle G1 v.2
