Can anyone date and identify this zipper please?

The attached pic is of the zipper type on a vintage leather garment bag I bought cheap for £10 at an antique fair, as the main zipper was shedding teeth. The zippers have the shape of Talon pullers so that might predict their age but I don’t recognise the CC logo. Can anyone help me please
Cheers

Ps I’ve managed to get hold of some brass toothed continuous zipper tape #5 so I’m going to have a go at replacing the tape and transplanting the original puller.

A bit more research brought up that it’s a Coats Clark zipper so I just need the age now thank you.
