This steel padlock was found near Rand Airport, Germiston, South Africa.
I have not been able to find any information on it’s origin or manufacturer, does anyone have any knowledge of this particular lock?

Information inscribed on the body. Hand Made, 4 levers, Eden & Co, in British Empire, Quality No. 136. There is also a stand alone number 225 in the top right corner.
I would appreciate any knowledge.
Thanks and regards
