Normally the frames with holes in the dropouts are Lil Holeshots or Mini racers.
But I've a photo of a Hutch pro Racer with such dropouts in the "rare/weird" section on my website.
It could be that the welder switched the dropouts.
There are also Lil Holeshot frames without holes in the dropouts.
Can you mail me some pics of your frame please?
thanks for responding iam 43 and raced hutches back in the day and i have never seen one lie this,the holes are small and inline with the dropout slots like chain tensioners the holes have smallnut and bolts in them .they look factory ill send you pitchures this evening.
