    Has anyone seen a lever banking set up like this ? A square “pin” is dropped thru the top plate and the
    lever End has a square shape larger than the pin.. Appears there would not be adjustments to the banking unless you would remove material from the inside of the lever square.. Watch is circa 1828 with a Thomas Savage on the movement ... Appears to have a standard table roller.. but I have not removed the balance to Get a good look..The curvey piece that looks like an extension of the square pin is behind the square banking pin is actually the stop works... it stops the lever ..

    It is hard for me to picture this from the images, but the description sounds like single-pin banking as on this John Cragg movement of mine -

    Hi John,

    I haven't seen single pin banking implemented in precisely this way, but yours is essentially the same as Jerry's example. novicetimekeeper has another with a similar arrangement.

    Regards,

    Graham

    There are many variants of this banking, though I have to say this is the first with a squared pin. Many of these escapements can be seen in the thread "Early Single Table Roller escapements.

    Regards,

    Mine is like Jerry's, a lever with a hole in the end and a single banking pin. Alexander Purvis, 4 Audley St, Grosvenor Square, 1833. It says patent on the dial but no idea what that refers to. Graham has some excellent pic of it from when he serviced it.
