The 1973 will be an Innocenti Mini-Cooper 1300.
It will have he following:
A GT type block with no cam chest covers
An 11-stud head
It will be left-hand-drive - there were no RHD Innos that I know of. I believe that was part of the licence build arrangement.
The final drive ratio will be 3.44:1.
Drive shaft couplings will be Hardy Spicer type.
Brakes will be 7.5" Cooper 'S' type
It will have a remote servo operating only on the front brakes.
Wheels will be as in the attached photo, as will dashboard.
There will be a red 'Export' badge on the A-panel.
The carbs will be twin HS2's on an alloy manifold.
There will be a header tank for the radiator (see photo)
The doors will have opening quarter-lights, unless it was originally a German market car in which case the quarter-lights won't open.
Dashboard will be beautiful.
Headlight rims will be different from UK made Minis.
It should not have wheel arch extensions.
There will be round side repeater indicators on the front wings.
Bootlid will be different in that the number plate recess will be square.
Exhaust should be centre exit as standard.
Gearbox will be the later rod-change type.
It will have wind-down windows and small full length storage bins on each door.
I have loads of detailed photos if that is any help, just PM me your personal email. Here are a few to be going on with and I hope they help. The Inno 1300 Export is a really beautiful Mini, possibly the best there ever was:
