Couple of pics attached (hopefully). Poor resolution, but it's the best my phone can manage tonight.
Clock details are:
Mahogany case, some minor dings and a little damage to the face, but nothing you wouldn't expect given its age. Movement is by the Hamburg American Clock company and seems pretty clean. Clock has Westminster chimes.
Value wise, I don't know if the plaque adds or removes value. Personally I like it as it gives it a personal History
