Thanks Grant.
Yes on page 991 there are indeed two such photos, but they are small photos and I am aware there are some other models that were created. I am not sure if the PP models have JL movements.
Some of the Hamilton, ie USA, models have a Hamilton marked calibre and there is absolutely no reference to JL anywhere. I wondered if PP were the same. I know they are rare birds and the Complete Price Guide to Watches values these at $100K+ -- hence my interest to authenticate examples.
