doing in the 1930's, but in 1952 there was a Miles Custer living in Las Vegas.

1952 phone book listing:
Custer Miles r514 Bridger Av....................................2113

The same listing is in the 1956 Las Vegas phone book.

We have a 1953 City directory, which shows "Custer, Miles Magnesium Bar 514 Bridger Ave...2113" Don't know if that means he owned it, or worked there.

That said....I don't know if that's the "right" Miles Custer!
