Window tilt latch

I have a house full of these windows . Great window I would assume higher end cost wise but no identification on them I can not find this tilt latch . It's a horazontal slide window that closes into it self so the window is flat when closed. There are 4 of these latches on both sides of the window . This latch is about 1.5 inches longer them the latches I found and the bottom Is a 1/4" plastic pin that slides in the window track . I can't find any latch that has a round pin . Any help would b appreciated
