I also noticed it has thin wheels on the front axle and thick wheels on the rear axle. The axle ends are untouched so that's original. The model has the early recessed ejector ring on the winch motor housing box. The thin front wheels show no signs of LESNEY being molded into the wheels.
Out of a random box of 13d beaters, I found three with thin wheels on the front axle and thick wheels on the rear axle. All three either had a flush ejector ring or a recessed ejector ring. None of the three has LESNEY cast on the front wheels (not even faintly). With the finding of three in a row with nearly identical casting features (and all three had decals), Lesney must have been using up the old thin wheels on the front of the trucks. Which brings up the question: Does anyone have a 13d with thick wheels on the front and thin wheels on the rear?
Regardless, I culled out the "Dad repaired" model and put it with other models that I find too endearing to restore or turn into parts mules. It's now with some other well loved models that each have a story to tell.
