It looks like the red switch used für 41CYs, so maybe W&W did the modification. Did you work for them?

Thanks for the image, I made all mine inside the battery compartment, better esthetics. IMO…

No I didn’t work with/for W&W, I was more of a hobbyist modifying 41s and 71s and all mine were done in DK. Hundreds…. But all in DK. as Steen P. (who wrote the HEPAX) a Dane
