vintage industrial office desk

This is a older industrial desk from maybe the 60's. It was for testing  parts for a aerospace company. the base is metal and it is very heavy.  Has a great look to it and I thought since industrial items are in demand now I should try to sell it because we need three or four people every time we move it. This is the first time i have used instappraisal and I can not find any similar items to compare it to. thanks for any help you can give me.
