Hi Dnil,
>well i am limited here as to what i can post. I did these jumbo size so yes can do much larger scans.
A bit larger would be great :-) I'm afraid some of the important details got lost, though the main text was OK.
I was surprised to read that the torpedo director is such a simple arrangement (though requiring complex handling)! Either the German device of which I saw a photograph was more advanced, or it just had a very fancy input box for the same functionality :-)
One difference at least is the German sight was able to adjust internally for different torpedo speeds.
Regards,
Henning (HoHun)
