I live for the CABE
Hi, late to the party, but I agree with Krakatoa and Mike,
M4, last quarter of 1943, 36 10, heavy duty spokes. Since only Military G519 bikes from Huffman or Westfield were getting these at this point, it's either off one of these, or a spare produced at the time. M4 would have been used on bikes at the very end of production.
They were originally Parkerised, and these has generally lasted better than plating. Here's some shots of mine from quarter 2 1943.
Below is the original arm, not marked S, but, as you can see, unplated. I have seen the S on other arms, but never thought about it.
I hope this helps,
Best regards,
Adrian
PS, pm'd too.
