A search of the 1930 Census records produced two possibilities:

Vernon Askew, Accomac County, Virginia
Vernon Askew, Shelby, Texas.

Both were born in 1922, which would put them at an appropriate age.

A wildcard search of the digital enlistment records with the value 38476*** returns no records. A search of 3847**** returns 884 records, most enlisted from Oklahoma or Texas.

There is some percentage of the enlistment records missing from the digital online database. There seems to be a block missing around this particular s/n.

I would suggest contacting the National Archives directly with this s/n explaining that it is missing from the digital record and see if a paper or microfilm record is available.
