I presumed this sight to be from an Italian artillery piece due to it using the words 'Parallelismo' and 'Direzione' but what gun would it be from and what sort of sight is it? It has what I presume to be the markers mark on top 'San Giorgio S.A' and underneath that 'Genova-Sestri'
My Flickr account has some better quality images and I'll try and post some of the markings on it if they come out okay
