Large Antique New Haven Oak Wall Regulator Style Clock 43" Long

This large antique New Haven oak regulator style wall clock has the beautiful original finish oak case and measures about 43" long. We hung it on a nail and it ran for 15 minutes o so then slowly stopped so it may either of not been properly level or it could need cleaning. There is a crack in the black glass lower corner  which you can see in the last photo that is not very noticeable and it measures almost 17" wide x 6" deep.
