The Philmore Manufacturing Company marketed JJ-38 type keys to hams
in this country in several packaging styles. This is a shrink
wrapped, hang on a peg board, package, which contains a standard
JJ-38.

Notice that this box is somewhat ambiguious about the contents.
Is it a JJ-38 or a J-38??
Well, it is a JJ-38 type of key, but there are several differences.
Notice that the lettering is not white, so it is difficult to tell,
but the front of the base is stamped J-38, not JJ-38. Also note
the molded in stay cord eye. They made it just "a little more" like
a J-38.
