4-door saloon.

Looks much like the Series E, but don't be deceived - this is Morris's first monocoque. Not only this, but there's also a brand-new engine, the XPAG overhead valve unit destined for long service in post-war Nuffield and BMC vehicles, so there should be no trouble with engine spares. Saloon is civilian body style available; a Utility ('Tilly') pick-up was made during the war. Saloon produced until 1948, so there are a reasonable number of Ten M survivors, although rust a very real problem. Post-war cars distinguished by more rounded grille.
