Thank you for your comments.It is shame to me I did not recognized Resch. The unusual gong mislead me. I think that gong in this clock is not original, installed later. I compared this movement with other Resch movement and they are similar.Typically Resch marked the serial # on the backplate, the mounting bracket and the top of the pendulum rod which this one has though the movement # differs to the one elsewhere. From recollection Resch mounted the gong on the backplate not the case though that's based on ones I've seen.
I think it should have a pediment.
