GILCO road signs reproduce only British traffic signs and are made in an solid mazak die-cast. There are approx. 30 different models, and they are only sold in boxes of 10 different signs.
The preventive models with a red triangle at the top are 6,5 cm high and the prohibiting models with a red circle at the top 7 to 7,5 cm high. These road signs are cast in one part: a large white base, an alternatively black and white painted pole, a large white vertical rectangle with black painted drawings and inscriptions, and a red circle or triangle at the top.
You can easily identify with the "GILCO" inscription behind the rectangular (white) part of the road sign.
