KT Porsche large tow cable

Does anyone know the correct diameter (in mm) for this cable? I am scratchbuilding the cables and want to get the correct Karaya set. Tamiyas measure at 1.5mm = 52.5mm or +/- 2.1 inches - does this sound accurate?

Nope that is way too thick.
The King Tiger tow cables were 32mm in diameter and 8200mm ( 8.2 m ) long
The track cable was 14mm in diameter and 15000mm ( 15 m ) long

Excellent - Karaya make a 0.9mm left twist cable for German AFV that will be perfect - thanks for the help!!!
