A new clue about the Ringel journey
We knew from Helga's interview with Walter that the family was first in Lyon, with the idea of getting through to Switzerland. (This is after leaving Nice sometime around June 20.) In Lyon, they saw Gestapo presence and thought they recognized the very agent that had tracked them in Berlin. They gave up on the Switzerland plan and returned to the Mediterranean.
This document shows that they then stored eight pieces of luggage in the town of Gallargues-le-Montueux before proceeding on their journey. This could be some time in the range of June 23-25. We think they next went to Marseilles but quickly reversed course to Bordeaux, probably on rumors of Sousa Mendes. They were almost certainly in Bordeaux and may also have been in Hendaye, but after Sousa Mendes had already gone.
Then they are definitely in Toulouse, where on July 5 they obtain a Polish passport, followed by Pichal and Gissot visas on July 11. A few days later, they are in Perpignan with documents and preparing to depart for Lisbon.
This receipt, which I have had for years but had not been able to interpret before, itemizes their eight pieces of luggage being forwarded by rail from the Gallargues PLM station to Perpinan.
