IKEA bed 1997, name according to description with exact designation?

Hello,

my problem: I found an Ikea bed frame in the basement that was purchased around 1997 or 1998. The dates are from memory and may therefore be incorrect. Now the problem is that I have no idea how to assemble the bed. Unfortunately, the assembly instructions are missing. Could you give me a tip on what the bed is called or even a hint on how I can get the assembly instructions? That would be great!

About the bed: The bed is made for a 1.40x2.00 mattress, in beech look, and has a larger headboard (see photo). On the left and right as well as at the foot, there is an approx. 10 cm long support surface. Otherwise, the bed is plain. Attached are a few photos (the big thing is the headboard, once with and once without flash, taken vertically, the right side is the side that goes downward; in the other picture, a few individual parts can be seen), which hopefully make identification easier.

Can anyone help me? That would be super kind! :)

All the best

Oskar

P.S.: I hope this is the right forum.

It *could* probably be from the Askedar series, I think I remember. When I google it, it at least looks similar. Only: How do I get an assembly instruction now? I am missing, for example, the article number and so on.
