Rabe,
My first reaction is PI+QL
Although the second plane in
http://cgi.ebay.de/ws/eBayISAPI.dll?...tem=6213855414 looks like PI+QR
I was correct there were three photos on or about the 12/09/05 which look like they are from the same or a similar series - possibly from the same collection. In all three shots an Ar 96 with code PH+PX is visible, and in one an Ar 96 can be seen with a code beginning VL+??.
