so we have a primary MLT of 2.127" and a secondary MLT of 2.755",
we know the turns of both the pri and sec, which is 750 T each,
so now we can get wire length - 750 * 2.127" = 1595.25" = 133 feet
and sec - 750 * 2.755" = 2066.25" = 172 feet
wire charts have DCR of the various gauges in ohms/1000 feet,
so we need to know what the DCR of our pri and sec winds would be if they were 1000 feet long,
1000 ft/133 feet = 7.519 and 1000 ft/172 feet = 5.814
so we multiply our DCR readings of the transformer by these factors to get our DCR/1000 feet equivalent, hopefully they should be the same as the wire for both pri and sec should be the same unless they tried to balance DCR by using 2 different gauges which is unlikely with a coil of this nature (cheap).
so 32 ohms and 44 ohms (pri and sec) = 32 x 7.519 = 240 Ohms/1000 ft and
44 x 5.814 = 255 ohms/ 1000 ft ,
MLT formulas are not exact nor does wire have the same DCR all the way through the spool, so we do not expect 1% tolerance from this method, but lets see if we can determine the wire gauge from the chart, hopefully there is enough distance between DCR figures to make a good guess, also, older wire does not always match up with today's wire and wire charts,
looking at the chart we see that #34 has a DCR of 261 ohms/1000 ft, the next gauges up or down give 206 and 330, so it looks like we have a match,
so the Triad A-57-J has 750 T of #34 for both pri and sec,
