This vintage men’s swim suit was made in the 1930s by Gatner Wikies, the originators of this type of suit.  The patent number on the tag is for a 1932 patent for a very similar pair of trunks- the patent, along with 1930s Gatner Wikies ads showing very similar models to this are below.  The suit has a hole just at the corner of the key pocket, and one at the gusset seam- because of the location, I would think a repair would not show too bad.  Otherwise, they are in very good shape.  They have a flapped pocket, diamond crotch gusset, white belt with a chevron and star buckle.  They have a heavy ribbed cotton lining in the front.
