Just having a butchers at
www.agriaffaires.co.uk and came across a 1/4 scale Foster Colonial tractor and an Albaret roller albeit converted with a two stroke engine !!!
Both items are under the tab of Antique Equipment with the Foster found under Antique Tractors and the Albaret under can be found under Antique Construction Equipment.
May be of interest to someone.
Oh, also under the Tab Antique Equipment -other there are many threshing boxes plus other stuff that could/may have an interest.
