    Updating this 2013 thread.

    Short Nose 275 GTB used 60 spoke Borrani RW 3874 wire wheels and Campagnolo Starburst alloys which were both 6.5" x 14" in size.

    The very early Long Nose 275 GTB also used the Campagnolo Starburst alloy wheels in 6.5" x 14 " size as well as the Campagnolo 10 hole alloy design in this size.

    Please see pic below from 6 Carb Alloy Long Nose 275 GTB #08011 showing the 6.5" wide Campagnolo 10 hole alloy design.

    Later Long Nose 275 GTBs used the Campagnolo 10 hole alloy design in 7.0" x 14" size as well as the 72 spoke Borrani RW 4039 in 7.0" x 14" size.

    great info.
    what about the straight eared knockoffs as seen above vs the curved ear knockoffs?
    also the embossed(raised) horse emblem vs the etched(cut) emblem useage?

    Well this hero drives his 275GTB pretty fast



    I did get him eventually, and arguably i should have made an earlier lunge up the inside earlier, but i'm not that way inclined.

    Further updating the 275 GTB wheels information: I believe that the very early 275 GTB Long Nose also used the 6 1/2" wide Borrani 60 spoke RW 3874 before the 7" wide 72 spoke Borrani RW 4039 was introduced on later Long Nose cars.

    Steve: What documentation do you have to support your statement?

    Was Alberto Silvera's special order #07993 originally supplied with wire wheels or alloy wheels? Look on the build sheets for the size of the wheels.

    Steve: The Build Sheet for 7993 does show 6.5 in wheels, BUT is does not state which kind. I have never personally seen a Build Sheet for 6.5 inch Wire Wheels on a Long Nose GTB. I have many Build Sheets for early Long Nose cars with 6.5 inch wheels, but they specify Alloy (Fuse) wheels. However, on 7993, the Alestimenti Sheet notes a number of special items including wire wheels. There are numerous instances of disagreements between the Build Sheets and the Alestimenti Sheets, so I cannot say for sure what specific wire wheel was originally on 7993. I personally have not seen a Build Sheet for a Long Nose car that lists RW 3874 or 6 inch wire wheels. I would like to see one if they exist.
