stompa scorpio bed with pullout sofabed - needs repair (Trinity EH5)

The photos above show a solid pine Stompa Scorpio bed (1990's) identical to one which we dismantled several years ago which has been in storage. It is a raised bed made from solid wood & has a double pull out sofa bed underneath & incorporates a desk with 2 drawers & a bookshelf. Unfortunately the screws to put it together cannot be found. There is no mattress for the actual bunk, nor cushions for the seat part of the pull out sofa bed, though we do have the back cushion which forms the pillows. The drawers also need a repair & from memory, there are a few small stickers on part of the bed. For anyone prepared to put in a little time & effort, this is well worth doing! This bed was used by 2 of my now adult daughters, then my granddaughter. It was fantastic having a sofa, desk & bookshelf & the pullout double bed was a boon for childhood sleepovers, as well as visiting adult guests. I've been loath to part with it but need to empty the storage unit where it has been housed as it is costing a lot of money storing things we may never have the space to use again. I really hope someone else can make use of this versatile piece of furniture!
