The minute markers jumped out to me.
I have my 2576 twins out as I am attempting to see if I can find the hour hand to the 2577, so I am becoming sensitive to such things. I am still considering what to do with the 14713-61 I stripped all the marking off of. Of course I have been wanting to build a pad printer for the last 28 or more years. The minute ticks, look like the hardest to get right. One needs a good dividing engine/pantograph. Digital divisions simply do not cut it. (pun intended.)
