ANODISED ROYAL ENGINEERS - TKS MAKERS MARK

[Ex Supt Clk RAOC]

Hi all

Attached (i hope) are photos of an Anodised Aluminium Corps of Royal Engineers cap badge, not at all unusual in itself but this one i found recently has the Toye Kenning and Spencer makers mark, TKS (reference Marsh 12.1 - TKS in an enclosed box).

I have not seen this mark on this badge before and just wondered how common or not it is? Common or rare it will make a fine addition to my collection.

Your comments would be most welcome

Regards
Steve
