Jack The serial number is 109091. The spring is indeed a big half circle. On the hammer rail was the inscription "Staib-Abendschein Co, NY". Might have been just Stab, or some variation, it was a bit smudged. There were two broken jacks, but I think I can get replacements, or modify an existing jack to replace them. Other than that the action was in pretty good shape. It didn't feel significantly different to play, in spite of being so differently constructed. I recommended she try to find another piano and get rid of this one. If she does so, are you (or anyone else) interested in the action parts for spares?
