The auction is long over, so now I can post my question. I almost bid on this HAC. The case was beautiful, and the dial marked with the crossed arrows. But, the movement wasn't, and that along with the hammer arrangement held me back. At first I thought it wasn't an original movement, what with the dimpled plates like a Hermle, no crossed arrows, and the extra clips around the barrel arbors, plus that strange hammer arrangement. But, after searching around, I became convinced the movement was a more modern HAC movement despite the lack of their logo. However, the hammer arrangement is something I have never seen, and I couldn't find another like it in all my searching. With no access to the original photos, I made a crude outline drawing that shows the arrangement. The hour hammer seems to be curved around and under the Westminster ones in order to reach the proper chime rod, but I couldn't tell for sure from the dark photo. There was five rods, so I'm assuming that's where the fifth hammer is. Hoping someone has seen this before so that next time I come across a beautiful HAC case with a movement like this, I can bid with some confidence.
