Rare BTC Ingersoll Elite Rolex Rolco 15j 10.5 Ligne Watch Movement Ref E

A rare 10.5 ligne Ingersoll Elite branded BTC movement as used by Rolex and Rolco among others.

Balance is missing a pivot. All other parts appear to be salvageable. It appears that the screw that retains the intermediate drive wheel has been lost and a replacement screw along with a modified AS 340 setting lever spring has been added. Please note there is no pin on the setting lever that would engage with the more usual type setting lever spring.

The movement is sold for parts spares or repair only.
