GREAT WESTERN RAILWAY COMPANY.

The buff funnel with black top was adopted in 1872 and replaced in 1873 by red with black top. That red livery lasted through 1964, followed by British Rail colours from 1965.

Reed 1891 and 1901 omit lettering on the annulet; it appears in the corrected 1912 version.

Haws’s charges and the larger Talbot-Booth illustrations differ in clarity: Merchant Ships 1942 and 1944 distinctly separate the two shields and crests, in line with G533. Merchant Ships specifies yellow edging to the annulet and black lettering.

Tenders used this funnel from 1909, with the letters also displayed across the bridge front.
