Merc and help needed on dating navy button, possibly CW

[Wallhangers]

Short hunt yielded just these 2 keepers. There is no back on this button and the only thing I found on google was an officer's button with a similar design but it had the gold gilt. Many of the similar buttons have the anchor rope wrapping at a different angle. If you can approximately date this one I would appreciate it. Thanks

Got a back mark?

The back of this button is gone.
