Hohner Western Series HW400CN


I have an Hohner Wester Series HW400CN accoustic, flat top (and curved back) cutaway guitar.
Can’t find any reference to it on google.
No serial number. Label say made in Korea - presumably South Korea?
Well made, nicely finished including inside the body, has really nice action and sounds good. Looks as though it may have a steel neck truss rod.
Does anyone know anything more about this model? When made? Production run numbers? Desirable?
