UP FOR SALE IS A VINTAGE SIGHT GLASS TYPE DRIPPING OIL CUP USED FOR ANY NUMBER OF APPLICATIONS, INCLUDING VINTAGE ENGINES, MACHINE TOOLS, LARGE GRIND STONES STANDS WITH BABBITT OR BRASS OR BRONZE BEARINGS, OR ANY OTHER CONTRAPTION THAT REQUIRES A CONTINUOUS SUPPLY OF LUBRICATING OIL. THIS DEVISE HAS AN OVERALL HEIGHT OF 5 7/8\" WITH THE OIL CUP AREA BEING 2 3/4\" HIGH & 2 9/16\" DIAMETER. THE THREADED PORTION IS 3/8\" MALE PIPE THREAD. THERE ARE NO MARKINGS THAT I CAN SEE THAT WOULD INDICATE A MANUFACTURERS LOGO OR HALLMARK. I HAVE THIS LISTED AS USED BUT IT\'S VERY POSSIBLE THAT THIS COULD BE NEW & NEVER USED. IN THE INTERIOR OF THE GLASS AREA, THE BRASS APPEARS LIKE NEW. THE ENTIRE OILER, WITH THE EXCEPTION OF THE TIN FILLER LID ASSEMBLY, LOOKS TO BE MADE OF BRASS. THIS HAS PATINA ON IT FROM SETTING FOR A VERY LONG TIME. THE MARKS THAT YOU SEE ON THE IMAGE OF THE SIGHT GLASS IS SOME TYPE OF PATINA THAT DOES CLEAN OFF. THERE IS NOTHING WRONG WITH THE GLASS. I LEFT THIS AS I FOUND IT. SOME LIKE PATINA & SOME DONT. PROBABLY, THE FIRST TIME YOU FILL THIS WITH OIL, THE EXCESS OIL WILL CLEAN UP THIS OILER QUITE NICELY. PLEASE ASK ALL QUESTIONS BEFORE YOU BUY! NO INTERNATIONAL SHIPPING! PAYPAL PREFERRED! THANKS FOR LOOKING!
