Large Ikea corner desk/workstation

All the details

This Ikea corner work station (bought 2013?) is very similar (but probably not identical) to Ikea's HEMNES Corner workstation. Original colour was black/brown but it has since been (not very expertly) painted white. It has been completely dismantled into its component parts and all the assembly bits are available. However, we do not have the original assembly instructions. As it is a rather complicated piece of kit, you would probably find it helpful to get a copy of the assembly instructions from Ikea, to help you reassemble it. A photo of the desk is attached.
