My 1950 Mercian R/P has Nervex lugs that on the top tube head lug and downtube head lug have SPEARPOINTS, I have not seen another frame on Ebay or whatever with these lugs, How many members frames have these lugs? Is there a Nervex catalouge that shows these lugs in it? To see what I am talking about go to LeCirque 2006 Dale took photos of the lugs. Cheers John Crump OldandspeardBrit. Parker. Co USA
