First, great article!

So great actually, that I tried to retrace your steps to see how it works. I've come to the point of extracting the (r,s) values from the transaction, found R and S1, but got stuck at the M1 value.

The R value is in all the sigscripts of course, since the nonce is reused, and the S1 value i found in the inputs at index 1, but the M1 value given in your article (483483...) I found in the sigscript s value in input at index 6.

The S2 and M2 values from the article I can't find at all..

Could you also add some extra info how to obtain the M values?

EDIT:
figured out the M values, with the help of these:
