TT,
thanks, I'll check them tomorrow, was told they were from a cb750.
the other two sets, one set is the same as what I have on my F1/K6 hybrid - but too greasy to check the stamping at the moment, the other 95% complete set are stamped 657B.
SO i probably have a bit of a lucky dip at the moment, a few more ice cream containers to go through yet- maybe some more surprises.
