Wittnauer 8-day clock

[AWilson]

My 170A had a 8-day clock installed as an option when it left the factory. I still have a 8-day clock in it but I don’t believe it is the original because the knob is in the 6 o’clock position. Someone cut the panel to make it fit but obviously the 7 oclock cutout still exists.

I would like to find an original working one. Can anyone advise what it looks like? And if you have one let me know.
Pictures are of my clock after I took it out.

From the photo of the instrument panel on pg 25 (Figure 6) of the reprint A model owners manual in the MX Library, it appears to be an A-11 type clock, the one with the large numbers. Google A-11 8-day aircraft clock and you will see what they look like. They were made by a number of manufacturers and at the time were readily available as WW2 surplus. Later models of the 170, like my ‘52 B model, had the version of the clock with the smaller numbers.
