Hello there. This operator looks like either our 39-253RB or 39-439B. The difference between them is shown in the video below. For the keeper, Hurd casement windows have been known to use our 38-144 Sash Lock in the past, which uses either the 38-276 or 38-277 Keepers. See if this hardware matches up. |
