Recent arrival Edgar Henn P1088 with that 500deg plus rotation. So when I first saw this one it reminded me of old "war of the worlds" movies alien walkers, so between that and the high rotation this clock has I had to have it. Anyway I get to the mainspring and it looks like a puffed cinnamon roll, think I should replace that? I'm thinking I should replace it. Had a chuckle when opening up the shell of the pendulum balls. Yes you can put a square lantern in a round shell. My other Eurmaca has the coach lamp pendulum shells with the same weights. Curious to see if its going to be 7.5 or 8 bpm. Clocks seems to be in decent shape other than being very oily and dirty. Looks like it was in the shop back in 1960 because they annoyingly used a knife to label it under the base. Wish shops did not do that..
