LMS steamer colour schemes

[Alasdair Allan]

Hi there - new to this site - thanks for having me! Looking to paint a model of PS Duchess of Fife (1903) as she appeared from 1925 to 1939. Wondered, does anyone know about two details of colour scheme for me please? Were railings white or silver? Were deck vents white with red lining or were they silver with blue lining? Have had conflicting reports! Many thanks if anyone can help. Regards Alasdair
