Description

There is no brand on this specific item. I have no knowledge of these. I had a family who collected these pieces throughout his life. He has now passed on in life. Trying to help out his family. Please review my pictures I have provided. Selling these as “parts not working” because I have no knowledge of these. Super cool lab equipment! You’re judgment is better than mine. Sold as is and no returns! There is residue in it. The tip is broken. Thanks!
