Ah yes, just looked at a photo of an S2A, and I see what you mean. My S3 already has the beefier arms, so I guess someone has already changed mine. I didn't realise they weren't always like that.Defender ones are more stable in that they don't bounce around so much.... Better arms and fixings, better that is compared to the series ones on spindly arms.
My series threes have both got them on, if you're going for originality though they do look odd once you know what they are.Ah yes, just looked at a photo of an S2A, and I see what you mean.

I thought they went into the same holes as later ones.... How do they attach?Mine has these, probably from its Army days. They are very solid, the arm is a solid bar. Mine has the holes for mirrors in the door hinges but they don't appear to have ever been used.
