Great historic picture! Yes it is the Anschutz 275 rifle, the rifle-type of choice for fairground shooting in Europe: a very reliable workhorse, that can stand the beating of endless dry-firing after the 4.4mm BB clip is empty. Quite an expensive rifle too back in the dayz (still is btw). Mine is amazingly accurate at 6 metres, always wondered if/what they did to it at fairground stands to make it miss targets...
