Thank you to all who responded. Definitely some very good ideas of things I will check out. The fact the shimmy comes and goes at such perfectly consistent intervals really has me perplexed. And based on the replies, I've come around to the realization that it could be something as 'simple' as wheel and drum balance. Thanks again.

Terry's idea of a lower rear end is pretty important. According to Stan, the rear on a car must be a bit higher than the front to stop shimmy.

There was a article about shimmy in one of the older newsletters.
Couple of things I remember are to check front wings for loose nuts and bolts fit of the doors.

Stan Gilliland wrote a detailed article on how to stop the shimmy in one of his parts catalogues. As I had previously stated rear springs sag with time and people tend to prefer cars that are lowered at the back. This is wrong for a Cord there was about a 2" gap between the tyres and the rear fender arch when they were new. Check the attached picture which was taken in 1936 with the original owner of my Cord. Allowing for the slight slope where the car was parked at the time. The rear end must be sitting up.
