Value of a Mersman Executive Desk?

I have a Mersman executive desk with two filing cabinets as drawers. The one filing cabinet has a locking mechanism for the drawer. I couldn't find much information on this style desk.

It is branded Mersman 104 88underneath. It is currently disassembled so I can clean it, however it is in excellent condition. The top has been covered with a protective piece of glass.

Any information would be appreciated, thank you!
