The resistance is not as important a factor as the number of turns. But, if you used the EXACT same size wire then the resistance will indicate if you are in the ballpark. If the wire is off by a gauge the resistance won't be helpful at all.

The 1-2 winding is the more critical of the two. It is the one that determines the frequency. 3-4 is basically a feedback winding similar to a 'tickler' winding and doesn't have much if any effect on the frequency.
