David Browns Tractor?

Question

What time period was the logo with the red and white rose on used?

Answer 1

I originally thought that it was from1939 until the factory closed in 1986 but I found this on the first link.

"The David Brown Company had it’s tractor manufacturing plant located in the village of Meltham Mills in Yorkshire. In 1955 David Brown acquired the old established firm of Harrison, McGregor and Company who were located in the town of Leigh in Lancashire. Harrison, McGregor were manufacturers of farm implements, their trademark ‘Albion’ was well respected throughout Britain and abroad. From 1955 to the late 1960’s a wide range of implements carried the name David Brown Albion and the rose badge integrated the two famous names."

Unless someone comes up with a more definitive answer you could always use the second link to the DB tractor Club where there many experts who will give you the correct answer.
