Thank you Steve,I know were the cables go on Biplanes like the HB W12 .According to Idflieg directive minimum 2 lifting points ( W 12,W19 ,FF49,= 2 ; Alb W4=4 )for lifting by crane were mandatory for seaplanes.The question is were do they go on the W29 without damaging the cowling/observers pit cutout when moved ?
