Yes the Red Hand of Ulster adopted as a badge by Rudge Whitworth in the 1890's. The sad thing is Raleigh Industries eventually stopped fitting the old heritage chainwheels to Rudge bicycles (and Humber, Hercules & etc) and everything got the completely bland and totally unimaginative omni-chainwheel that Raleigh came up with as a replacement. Raleigh even got rid of the really nice heron motif chainwheel that their own bicycles had worn proudly for decades!I wonder how many people know the significance of the hand motif on that chainwheel.
Unfortunately good Rudge chainwheels are getting hard to find as folk like to buy them as a 'collectible' to hang on the wall or rafters of their garage. Actually Rudge anything is getting hard to find which is only to be expected I suppose for a bicycle that hasn't been made for fifty years. (sigh)
