JAPANESE SCIENTIFIC INSTRUMENT Vintage MARITIME TEST PROBE Hydrometer? KSF Tokyo
A vintage Japanese Maritime Test Instrument housed in a custom Wooden Box.
We are pleased to present this vintage Japanese Scientific Test Instrument for your consideration. We are not sure exactly what it is, but believe it is a Maritime Test Probe or Hydrometer of some sort. The Instrument has a metal loop at the top. Below this is a compartment with a visible numeric scale. The compartment has a sliding door which can be closed. At the bottom of the Instrument is a large leather pad that is about 5 inches in diameter.
The outside of the Wooden Box has a metal plate with english characters reading
K.S.F
. The same
K.S.F
. appears on the Instrument's scale, followed by
TOKYO
. We did not find any other identifying marks (in English).
The Wooden Box measures 6 inches high, 16 inches wide, and 6-1/4 inches deep. With the Instrument in its custom cradle, the Box weighs 7 pounds 11 ounces. The Instrument itself measures 14-1/2 inches in length and weighs 3 pounds 12 ounces.
The condition of the Wooden Box and Instrument is very good. The leather handle on the Box is broken, but the Box itself has functional hinges, latch and lid. The finish around the exterior screws has darkened, with the wood showing some small splits at the screw holes. The leather on the Instrument shows some wear at its two ends, but nothing significant. The shiny chrome area surrounding the scale has some dried material that looks like varnish. All pictures show the actual Instrument that you will receive.
This is an unusual vintage Scientific Instrument, housed in a custom Wooden Enclosure. It would make a wonderful addition to any collection!
