Hello Kevin
Having got as far as I think I can with Mr. Reith I very rarely visit this site now and therefore I very much regret being so slow in responding to you but I don't have much more on him.
I was asked many years ago to research this man by a friend of mine but because the internet was very much in it's infancy such research was very hard going and almost to the point of being an impossibility.
My friend had purchased some medals of Mr. Reith and a photograph of him but having completed my research as far as I could I handed it all back to him.
I will try and get what little documentation that there is back from my friend and let you have a scanned copy. I will need your email address though to send them.
Regards
