This camera i got from my military uncle who was in world war 2 gifted to my dad, When studied history of it was surprise that Dallmeyer company use to make special prototype lens make to order for Vinten company during war time and i am happy that this camera survived during war time.so this is history that we are getting though i don't have papers for it but from condition and uncle told it was lucky that we have this lens survived and not much details there about it . It's best for super -six lover to add to there collection this precious vintage thing.I have not cleaned or serviced as i don't want to loose its originality. Camera is not tested. So selling as is .. Please see image to get idea about condition of camera and lens .
