Hi Rainer, thank you for the reply, I notice that Convoy Web lists the ONS convoy series only lasting from number 1 until number 51, with Cristales and Dartford thus listed in ON-92 and ON-100. The Calabria, also from CW, they list her sailing on November 21st, the same day as SL-56, while SLS-56 had sailed on the 19th. Regards John
