The name of the system for that panel is the "Peterson" if you look up "Peterson preamp" or Peterson power amp" here or online you should be able to find the information you're looking for on them.

I have a similar piano with similar issues and trying to decide what to do about these hammers. The piano I just purchased is an all-original, and fully functioning Piano "Celeste", 49 Key. It has a pedestal bump, and a Jordan preamp, and it's in very nice shape cosmetically, but the action is not great. The previous owner's dad was a producer at Colombia Records in LA in the 60s, and apparently Leo Fender gifted this to him. It was then immediately given to his 12 year old son, who has had it ever since, and I don't think he ever lifted the lid.

looking at a few of them.... there is a very slight curve in them, not sure if thats just from use or if it is intentional. wouldnt be surprised if they were marcel though. i did have to sand to remove the old glue but i only used 220, and just enought to remove the old glue/felt remnants.

Why wouldn't they straighten the tines on the tonebar? I was planning on doing that in a few cases.

Does it imply it has been replaced by a MarkII one or something like that at some point of its history ?
The seller forgot to mention it and as newbie as I am, I didn't check...
