Thanks for the great review and pics, Lello.
I too always suspected that the supposed great difference was more of a legend than a fact -- with exception for the lever rubber tube, naturally.
But I never accepted to pay $$$ for a loose lever fix that I could make DIY at no cost, so I have no Jimmy's CG and I can't tell it really.
I have to add that I find the loose lever the worst flaw in our reps, though.
On it, even a child can tell a rep from a gen. Other than those details about date font, back numerals, and so, that we love so much speaking about!
