Is it a Mappin

[Warren63]

Hi all, I acquired some Whitfield safe keys and two in particular urged me to find out more. The keys were all Whitfield safe keys so I am presuming the wire bow is one also, there is a number on the shaft and I was wondering if this is an extremely old one compared to the others because I have never came across another with the wire bow on a Whitfield key? The other key has an extra projection for four more sliders coming out of the end and pictures I have seen seem to suggest this is a mappins key and I wondered if anyone could confirm this. As I have said before I am a collector who has very limited knowledge and any help that more experienced members can give is greatly appreciated. Big thanks.
