Soulfire stereo pressings

The Flames Soulfire album was pressed in South Africa in true stereo in August 1968. Here are three pressings which have all been made on different machines or using different matrices. The differences are apparent if you study the perssing rings or ridges under the paper labels. The paper labels themselves are identical. The vertical column of track numbers is a little untidy. The number 5 is moved slightly to the left in all cases.

Note the pressing ring near the outer rim of the label, just to the right of the letter O in STEREO
Note the second pressing ring just outside the central portion, running through the M in SRMG 51234 A
Note that there is only a clear central portion and no other pressing rings
