For the top board, you know the dimensions of the ic, so you can determine the scale to get the board dimensions. The pin spacing is most likely 0.1" and the hole size 40thou or 1mm.
The second board might be a bit trickier.

Found a better picture of the second one:

 

 

According to GIMP and my powers of educated guesswork, the center spacing between each pair of holes on the bottom is 1/8" (not exactly standard is it) and the spacing between the pairs is 0.3" from center to center of B+ and B-.  The center spacing between the two on the top is (obviously) .3 "+ 1/8"+ 1/8" = 0.550".  Lengthwise spacing is 0.9".  Hole size is about 43 mil.
