In 1954 we Gibson already had block inlays on the Les Paul Custom, so dot inlays are not typical of that era...
Blocks on Vs were 75-79 in terms of production I think, and then quite small unlike the LP Custom. I don't know what the rationale for issuing them was.
But I think the Flying V is an interesting case regarding Gibson design aesthetics anyway. Both the 50's, 60's and 70's models all had the controls on the scratchplate, a decision that on any other Gibson would be deemed cost-cutting, or a departure at least from the classic through-body-control-cavity arrangement.
Both the early Vs and the 67s-onwards were dots as standard too (until the 75 option), and though there were short-runs like Bolan's walnut model, there appear to have been no student/standard/deluxe type catalogue/production options like P90s, binding, crown inlays, ebony fretboard, gold plating that you see on the variants of Les Paul, SG, Firebird etc?
Now over 60 years later we have seen so many copies, variants, custom models, user-modifications and evolution of styles and requirements, meaning the true intent of the designer and manufacturer may well have been lost or misunderstood. But with our passion for guitars and all their variety, perhaps we are the winners if for the most part we can still get to look at them!
