The Fiat G91 was a light tactical support jet fighter flown by the Italian, Portuguese and West German airforces in the 1960's and 1970's
The model is designed for the "Detail" type material. "Transparent Detail" gives a nice effect for the cockpit.
The miniature looks somewhat rough in "White strong & flexible" , as you can see in this review
at the "Microarmor Mayhem" site. The model is also mentioned in "Just Another Wargames Blog"
