This is a set of original E-Type Series I 3.8 “late” seat adjustment rails. These were used on cars from 1962-1964 featuring the wider bolt spacing and larger seat adjustment range. The end of each adjuster lever features the late “A.W. CHAPMAN, LTD”, “LEVEROLL”, and “LONDON S.W.6” markings. Right lever features the patent stamp. These are the adjustment rails only.
