Roberto,
My approach to this would be to not order parts until I have the action in front of me, at this point measurements could be taken and after a discussion with a supplier, an order placed. Even better would be to purchase samples from suppliers so you can compare at the action different options before ordering. I have no experience with knuckles on a SD so there is undoubtedly more expert opinion out there, however, I use the above approach for all my action retrofitting regardless of my experience with a particular manufacturer.

Subject: Fw: Baldwin SD- knuckle diameter
Hi all,
perhaps somebody could help me. We will repair a Baldwin SD, Renner action. The piano would arrive in a week but I need to know the diameter of knuckles because I have to order a set of them in advance.
Thanks.
