hi trying to id some vintage rods i came across and suggestions for uses
firstly these hymet deepex r0309, cant find any info atall
then chromoid 5, seem to be a standard that went obsolete in the 70s?
then these armoid 1 i can find the modern equivalent but does anyone have any suggestions of what they would be useful for apart from armor plating?
many thanks
