It's a 50s to 60s HA1 Clone, made by any one dozens of Japanese manufacturers and badged for whoever sold it.
Look underneath; is there a J- A or J- C number cast, stamped, or inked underneath? If so you can tell who made made it.
Also some of them will actually have their manufactures name there. My HOTHER (avatar pic) was made by JUKI. Has JUKI stamped on everything.
