Those sewing machine oilers from Amazon look practical...actually vintage sewing machine oilers are kinda where my head was at...a search on eBay shows quite a variety from cheap poorly made to expensive works of art...sometimes called thumb oilers.
The ones I like have small tank maybe the dia of a quarter with sometimes over 6 inch long spout. If I find one I will post a pic
Not sure if the thumb type would dispense steam oil...
This one is nice copper color but short spout.
