Musima De Luxe 25K Electric Guitar, DDR in the early 70's

Deluxe 25K is a shortscale Lespaul variation that was produced in DDR in the early 70's. The body shape is a bit different from LP's, it is more like Nighthawk/Blueshawk Gibson, but as soon as Nighthawks were introduced in the early 90's there must be no connection. There's a possibility that Gibson Nighthawk design was inspired by Musima Deluxe 25K, but I'm afraid this idea is too crazy to be true. The body was slightly carved (see the pictures) from both sides.
The letter "K" probably stands for "Kinder", since this is a shortscale.  cheesyguitars.com
