Yes--that certainly seems to be a high likelihood!
And the manufacturer was clever. The heavy keys are very nice Nic/Sil (but file marks are left on the undersides), and the springs are excellently crafted and very responsive. This is excellent news, because they would be quite troubling to remanufacture--at least for me. The post screws are the best I have ever had the pleasure to work with, and the body is exceptional. If clearly not made of the finest wood, at least they chose well for strength. (The springs bear directly on wood, and wear is virtually non-existent. No cracks (yet) at all, and socket rings are present and tight. There are a couple solid, tiny blemishes, near the top of the LJ--about a third the size of a pea, each, and close to one another. Upon initial inspection, I supposed that it must have been pinned. However, I see no other indicators of a split, and reckon that there were some surface imperfections that were filled in--due to a "seconds" blank.
In any event, I have decided not to restore her. She is clean, and just fine as--is. I have given her a decent cleanse and lube, and someone else can either do the same or better in another 100 years. She's still drinking on some almond oil, but she's been wiped down, disinfected with orange oil, (she was filthy, like window decor in a coal pricessing plant). I have also gently cleaned and disinfected the pads with vinegar, and a quick swipe with isopropyl. Afterwards, I conditioned the pads with leather lube, in an attempt to preserve them more for historical reference than for playability.
Now I am off to find some Coats and Clark matress thread in crimson, and the elusive replacement thumbrest, and I will call it a day on this little gem.
