Set of 4 Vintage Oilers

I’m parting with my collection of old oilers!  This set includes one that has been whimsically painted with lady bugs!  This would be decorative only….  One of the smaller oilers is copper.  The small oilers were likely for household purposes such as sewing machines.  These are oilers, so there may be some residue on them though I have cleaned them.  A fun, industrial decorative collection!
