Ahh, so it has. I was just, um, reaffirming your brilliant guess.
This is one of those things that gets in my brain. Today, I figured out there are 14 known-of inhabitants of the Southern Tombs of Amarna; I have tried to work out a way to fit “14 kilopascals of gravity”; and pondered whether there were 14 karats of graphite in a five point diamond.
Then, I went insane.
The best I’ve come up with is;
14 kinds of goal in a football player’s dream. Then I thought it could be ; 14 kinds of game in a full premiership diary (for those who don’t know, the premiership is the the top football division in the U.K) but , as there are only 20 teams in the premiership, that doesn’t work either. Working on it.
How about this:
Maybe we are missing an equal sign (=). try it like this:
14= k of g in a f p d
example: 60= s in a m (60= seconds in a minute)
Here’s a link to a puzzle in this form http://www.aztil.com/Fun_Zone/mental_test.htm
Tar! Feathers!
Sorry guv, but that doesn’t change the meaning.
7 days in a week and 7 = (the number of) days in a week are effectively the same.
It does change it a bit in my mind. It doesn’t need to be a common phrase. Maybe 14 is a date, somebody’s age… I don’t know.
Hey, this things driving me mad too!
14, d, f = 14 days in a fortnight, somehow?
I thought of this last time the full ptolemaic dynasty idea circled around.
The Ptolemaic dynasty was a hellenistic dynasty, a greek dynasty. So how about:
14 kings of greece in a full ptolemaic dynasty
Mine was the original posting on this and in six pages is still the only one that comes even close to making sense.
14 Krugerrands of Gold in a Fully Paid Deal

Damn, thought I was getting somewhere with 14 kilotons of gunpowder …
It’s more or less the power of the Hiroshima bomb, depending on where you look.
(fission powered device?) (Fissile plutonium?). Back to the drawing board.
Oops, so you did. Sorry about that. I agree with you then.

14 kinds of glass in a fiat punto dashboard?

I believe the answer you are looking for is:
14 kind of games in a full poker deck
that is the number of variants of the game (like omaha, texas hold em, no limit texas hold them,…)
I am working from memory so I might be wrong don’t I don’t think so 
best regards
I can’t find anything in a net search that verifies this. While most poker games are a variation on 5-card draw or stud, the variations far exceed fourteen.
I disagree that it’s close to making sense, since Ptolemaic rulers were not called Kings, and ruled Egypt, not Greece, and there were more than 14 of them. There were even more than 14 named “Ptolemy.”
I continue to believe it refers to something you’d only find in the magazine that had the puzzle. “14 kinds of Geo in a full page display.” Something we’d be unable to verify without a copy.
Twice. (Post #20). 
Kings of 'Gypt… heh.
Maybe they left out a . as in 1.4
While there were 15 Ptolemys, only 14 held the position of ruler of Egypt; there are some 400,000 hits for “king Ptolemy” on Yahoo!, many of them reputable reference sites.
