Semi-close ratio gearbox - South Australia

Looking to get rid of a few parts I thought I'd use and are still sitting around.
 
Starting with semi close ratio 4speed. Not sure of its actual name or where it first came from? Possibly Lotus or 2000E?
 
1st 2.97, 2nd 2.01, 3rd 1.39, 4th 1.00.
 
Was removed from one of my Mk2 Escorts but is not factory item to that car. Has Cortina style extension housing.
 
20 spline input and output shafts.
 
Looking for $1500 obo
