cheers mate i never thought about allen bolt. when i took it off with a metric it was baggy, so could be a result!!
it does look a bit rough but i literally just took it of a bike thats been sat in a garage for the past 20yrs! it should polish up ok.
so did hutch do donut clamps with no marking??

apparently they weigh 65 grams so put it on the scale and POW!!!!!!! 65g dead on

so I've started to clean it up
