Hello Mariano,
I am a volunteer at an aircraft museum in England (
http://www.shuttleworth.org/) ... we have a 1938 Bofors gun amongst the exhibits. On airshow days we set it up so that visitors can operate it and try and track aircraft. During this winter we have to start some maintenance and also try to reset the sights, which seem to be aimed badly. We are also interested in the corrector that you dismantled, and want to find out more about how it operates. Would you be willing to share your knowledge and experiences with us ? For example, how do you remove the sights ?
Many thanks
Richard
