there is a strange stamping on the face of the dynamo fitted to my'42 WNG, I believe the dynamo to be an original LM the stamping is of the letter R in a triangle, no idea what it signifies. kind regards

Two photos of the NOS speedo with the S on,it has a brass bezel,the photo of the back of the speedo shows some numbers (codes).

Hi Steve,
Mine has exactly the same numbers, Another mystery' All the smiths bezels on my other bikes are chrome plated brass so maybe the steel bezel is late/post war when brass was in short supply (Bullets/shells?) the plot thickens'
