m: perhaps we should expand this as m(ilites); this abbreviation is found in the pridianum published by R.W. Davies and J.D. Thomas, JRS lxvii (1977), col.iii.15-16. The other possibility is m(odii); elsewhere in the tablets m = m(odius) is usually marked as an abbreviation, but this is not always the case (see No. 4.14, 21).
Traces after lxi may or may not be ink.
There is a horizontal stroke above the first two letters which presumably indicates abbreviation.
In line 6 we now read: ] s(emissem) (quadrantem) (asses iii) s(emissem).. The last trace may not be significant.
Perhaps iii, ligatured at the top as in No. 4.23 etc., or possibly ]ti. The following c appears to have interpuncts preceding and following (though the first interpunct might be a serif to the last i); perhaps compare RMR 129.6 where a · c · is expanded as a(rmorum) c(ustos).
For the first two traces cf. line 5. The following d is difficult since it looks much more like b. To read d we have to ignore the apparent serif at the top left and treat it as part of the horizontal stroke over the previous two letters; the apparent tail at the bottom right of the hasta must be part of the following c. The number (670+) is very much larger than any of the others, but it can hardly be taken to indicate a strength report or something of the kind, since it is too large for a quingenary unit and too small for a milliary one.
