No, no, Wim, that wasn't my point. I know you were recommending replacement, as most would. However you suggested that repining will provide a satisfactory fix for a period of 75 years. IMHO, any fix that lasts 75 years is a permanent fix - and what then is to recommend against a permanent fix? I don't have the experience of repining action parts with verdigris and then observing how long it takes for the action to slow up again - but my general understanding is that the problem would commonly reappear in relatively short order - maybe just a few years - or less - but very likely within a decade or two at most. My point was that my best guess is that repining a verdigris action is NOT a 75 year satisfactory fix. Maybe someone with better experience can chime in.....
