Seth Thomas Regulator #1 Extra Round Terry Movement Antique Clock Second Bit

Round Seth Thomas #1 Extra Regulator Terry Movement Marked “X”. This is the same movement and mark as what is in my ST#1 Extra in my collection. This is the 12 sided topped clock from the catalog. There is a seconds bit that should attach to the end of the escape wheel pivot. It would have a 9lb 13oz cast iron weight. One thing to note is the knurled beat adjustment knob on the left has been replaced. See all pictures and ask questions to ensure satisfaction. Thanks for looking and follow my store as I’m adding more tools and clock parts all the time!
