huh? 
  
I've been a lifelong Z owner, and I've never seen a Z badge like the TK one on any Z past or present.  The scripted badge is actually a range they do for a few cars 
  
Didnt want to say anything till an expert came along!! TK only used to put the front (not a z badge) and the rear on cars that they modified... It was only demand from the US that meant they started to sell them to the public! 
  
only reason i thought it was an old symbol was because of these

i've seen other versions of oil caps and rad caps etc. and always referring to datsuns never nissans, so i thought it was for a variety of Zed cars 240Z up etc. 
  
Datsun Freeway themselves are simply taking the Z that Datsun used on the front hood, and side C pillars on the 240Z-280Z, and using that font for their own accessories.  Pretty standard fare, it is afterall, just a Z.  A similar font appeared on the later Z31.  Z32's used a revised version of it.  The Z33 did away with it though you'll see several firms offer badges that use a variation of it for the hood and hatch (courtesy, for example - I've got the Z badge on the front of my car) 
  
TK mixed it up a bit (if you will) by using more of a Chiller type font, and doing it in red (which is sort of their color).
