who made the Wreath Ideal Pen?

Can somebody help me identify the makers (and any other details about)
of the Wreath Ideal Pen

This example was found buried.

The clip end of the cap is broken and the thread of the cap is now
fused to the body.

There is no filling lever on the body. The end suggests that the pen
had a screw-mechanism piston-filler, or possibly a vacumatic design.

The only clues to age are associated items that indicate a date of
around the late 1930s or early 1940s.
