Krick Grunau Baby glider Plans Wanted

I’ve inherited an old Krick kit of the 1/6 scale Grunau Baby IIb glider.

Lovely kit, beautifully cut-out parts, everything there except… the plans to build the fuselage. I could probably work it out, eventually, but it would be a lot of hassle to jig it correctly without the plans.

Does anyone have a set of fuselage plans for this kit I could either borrow or purchase, or even just to copy, please?

TIA,
