Casement window replacement latches

I need several latches that come from an unidentified window but on one opener part
it says A.W. Anderson, Los Angles, Calif. patent no. 4364201,4571776. The opener arm says Truth with their symbol. The latch has a metal handle with a hook , two small ears and is mounted to the window frame with a plastic face frame that also holds the ears. The keeper is silver metal mounted on the sash.

Actually, the name on the part was Anderberg, not
anderson, so dirty I couldn't tell. Also there is information on that part that references a British company and one from Australia I guess somehow involved in the manufacture.
