Hi Axel,

These should be the relevant files regading these losses.
I will ask Rainer and Platon if they have these files at hand.
If not, I will be at the National Archives at Kew for two weeks as of October 16th and can have a look for you (or maybee Rainer as this is more 'his area of research', perhaps they are already on his 'to do list'.
By the way Rainer will also be there as of the 16th for one week and Platon will then join us on the 18th for one and a half week as he will leave for home the same day as i return back home.
Kind regards,
Brian Corijn
