Here is a lot of 10 brass engine oilers. 7of them are Essex brass corp (2 1/2 diameter glass)., 2 are Lunkenheimer #4, and 1 is an oil-rite (2 inch diameter).  They are all in used condition and most of the Essex oilers have a missing or damage fill door. That is the the little spring loaded flapper that is used for refilling.  There is also a top knob missing on the one lunkenheimer.  I cleaned them up a bit but there may be a bit of old lubricant left in them.  Some of them had been painted with green paint which I removed what I could of it. The glass is all good and not cracked.  I only ship to continental US.
