Because wheelsets are not returnable so I got to be sure. (I'm looking at some Miche Pistard wheels from Retrogression.)
Dropouts don't have to be exact but a 120 rear wheel in a 130 frame is not so good. If his frame has rear facing rear dropouts it's probably 120mm.
If forward facing dropouts like and olde road frame, they could be 126 or 130 or if really olde, 120. Some companies even specced 128mm dropouts during the 126-130 transition years.
