Ok, since my last posting, I have now done some research and established that despite the name Seth Thomas on the face of the dial, this is not a Seth Thomas clock. It in fact a Japanese clock Seikosha. You will see from the pictures below that the only mark anywhere on the clock is the trademark on the movement frame. The pendulum is not correct for this clock, I fail to understand how it found it's way among the box of parts sent to me, the seller is none the wiser either. Anyway, I have attached a picture of the complete movement and associated pendulum (I found these on another clock forum). I would appreciate any comments anyone might have about this clock and it's movement. Also, advice on where I can obtain a pendulum like the one in the photo?
Thanks,
Richard
