Trawling the web for information on Molnija pocket watches I found numerous references to Cortebert, both in the lineage of the 3602 and as suppliers of watches to several national railways.

Serbia, Egypt, Poland, Turkey & Italy were regularly mentioned as awarding contracts to Cortebert for railway watches.

Being a bit of a compulsive collector of 'sets' I decided to see if I could collect a Cortebert as supplied to each of the national railways.

Turkey, Italy and Poland.

Serbia and Egypt elude me completely.
