They're Chinese made parts, I believe, although I thought the the hammers were still Renner. Initially I was finding a lot of (very) loose hammershank pinning, but that seems to have been corrected either at the factory or with the OEM. The capstans are also anodized aluminum, are lighter, and need no extra lubrication. The other problem I was seeing was that of rep springs squeaking in the grubs - a problem that I've also noticed on Tokiwa parts. If you raise all the hammers and slowly depress the rep levers you will hear it if it's a problem. Generally I'm finding that the regulation is coming through quite close, although I did prep one just the other day where the rep spring tensions were generally on the weak side. - Mark Dierauf johnsond wrote: > <div class="moz-text-flowed" style="font-family: -moz-fixed"> > Hi- > > Does anyone know more of the story regarding changes in the action > parts of these new Masons?
