2001 Keystone Springfield Bedroom config

[gametro]

Hello All. Just recently purchased a 2001 Keystone Springfield 195FLL Clearwater Edition. I was made aware that the previous owner reconfigured the bedroom to take out the top bunk. He left what I think is the old bed rail along the walls (3 sides). Does anyone know the bunk board is made out of and how it is configured? I need to put the bunk back in place over the double bed. Thanks in advance!
