Investigating a little further on the net armed with the information youve both supplied , ive found a bakelite version made by the winter company for Luftwaffa Bombers in WW2 ,however mine is a metal version so im not sure if my version is more modern or not.
I might actually contact the Winter company to see if they can shed any light on mine as they have a History section on their website so hopefully they have some archives.
