White plastic 6" mirror as fitted by Leyland from Late 1970-75.
Also found intermittently on earlier cars but original grey fades into white.
The first 6" light grey plastic mirrors was patented in 1962 but were first fitted from October 1964 through 1965 and had a twin ball stem with a black rubber sucker which slid on. The twin ball stem was replaced with a 3 ball stem 24A2111 in late 1966 which had the extra ball on the stem centre where a new clear plastic sucker
CRT10004 was attached.The early black sucker type was fitted to cars with sun visors that had a hinge at one end and a clip at the other.
2 styles of mirror head caps were fitted and the other style is available as
47H9649 and
47H9649WHITE if seeking your original style which have to be purchased seperately
When they introduced the sun visor with hinges at both ends in 1965 they started fitting the 3 ball mirror stem shortly afterwards.
The white mirror was introduced on production cars from MK3 1970 on but seems to be found on some earlier cars although many look white when aged and blemished by the sun. It is only when you look behind the glass of the mirror or inside of the foot where it attaches the body the true colour can be seen.
Most Leyland/BMC/Rover aftermarket mirrors were sold as grey-
see
24A1750 but both white and grey 6" mirrors appeared under this part number by Rover and then winguard made a 7.25" after market mirror in white to confuse all..Most Mk1 and Mk2 originally had grey 6" wide mirrors
