[Miura Iron Shaft]

I have an old retro 2 iron tournament blade.  The shaft band states, KM1024, stiff.  I assume KM stands for Katsuhiro Miura.  Any idea what modern shaft would be equivalent to it as I want to shaft a 3 and a 4.

 

Thank in advance for your help.

[Identify Miura Blade]

I recently picked up a used 2  iron and actually seem to hit it quite well.  Can anyone help identify this blade.  The font looks different from most Miura clubs I've seen.  If it is a counterfeit it actually hits and feels quite good.

 

Thanks in advance for any information.
