The case pictured turned up recently and I think that it is from the Hotchkiss 53mm revolver cannon, although as it is without markings I am going by the measurements alone. The rim is 66mm, length 186mm and mouth 53mm, with some damage. Initially I thought the primer was false but it appears to be correct and has an internal part inside the case. Pictured alongside a 53x177mm Gruson case for comparison. Glad to have confirmation of my identification and any thoughts on a date. Many thanks to Tony Williams, identification based upon data in his ammunition data files.
