The clock slightly leans back in the resting position - the upper part slightly behind the brackets and the bottom slightly in front of the brackets. I can straighten this easily enough - it seems to just be a function of whether you want to tighten or loosen the bolts on the sides.
I hand-wound it just a few times and it is still going very nicely on day 2. Assuming there was a key at one time, I do not have it for this clock. A VERY NICE ESTATE SALE FIND IN NICE CONDITION!
