Here is an 8 port Madisin Kipp mechanical oiler or lubricator Model 50 No. This oiler is complete and seems to be working as it should. Everything moves freely and easily. It is in just the condition I found it in, all oily and greasy. I lightly cleaned the tags for pictures but have done nothing else to it at all. Please look at all the pictures and decide for yourself if this is an item that you need or want.
