Both dropouts look like the mouth end is slightly narrower. See if the axle ends will fit by sliding them laterally into the top of the front dropout and back of the rear dropout from the outside of the dropouts. On the rear dropout, don't forget to set the adjuster screw as far back as possible. If you can do this, the mouth ends of the dropouts are slightly pinched. The axle end for the front hub doesn't look so oversize that it's the next size up.
