Western Wheels was another mker of that style, & IIRC the Gurney was their model name for it. They look nice polished.
PS - they are aftermarket, but were period correct & available from Porsche+Audi dealers, tire shops, etc. back in the day. My buddy's car below was equipped by the SoCal P+A dealership when he got it new. See the O&H Wheels & Tires link below for the OE options - depending upon what year yours is, they could be one of 2 steel style wheels, Pedrini, Mahle "Baby Gas Burners" or Fuchs 2 Liter Alloys - all in 4 lug.
My buddy has some on his OO 71 914/4 with <62000 mi, so that's what his were called.

His & most of them are not the 914's 40 ET offset, so they tend to limit upsizing tires due to tight fit in the rear wells, ergo 165 was about the biggest he could do with only about 1/4" - 3/8" clearance to the fenders (fenders not rolled to flatten the lips), ergo spacers make it worse.
