Two pairs (4 pieces total) of mainsprings taken from old grandfather clocks. They were removed from two clocks. One is slightly different in color, but I don't think it will affect its function. However, they are old, so there is dirt and grease. Width (thickness?) is about 1.9cm. If anyone can use them, please consider. #Seikosha #Aikosha #NagoyaClock #MiscellaneousGoods #SmallItems #Antique #Retro #Object #TimeSignal #Time #Showa #Taisho #Meiji #Metal
