Quoting the passage under section VII, Miscellaneous Accessories:
Sheet steel shielding of sensitive parts against flying rocks and ground scraping for all models.
Just as well, under section VI. Extra Special Equipment, there can be found:
Special Export Version A: for extreme climatic conditions and bad roads; all models except 300SE will be equipped accordingly, upon request.
Special Export Version B: for extreme climatic conditions; all models will be equipped accordingly upon request.
I'm supposing those special versions were equipped with various options that exist elsewhere in the catalog depending on the customer's needs. I can see stiffer springs and shock absorbers, low compression ratio engines, high altitude parts, carb de-icing (like an airplane!), and various other options.
But back to the point: were any W113s equipped with such special equipment, particularly undercarriage protection? What did that look like?
