Vintage Aqua Survey Compass-Locator
'dip needle' or 'dipping needle' compass.
Marked "AQUA SURVEY AND INSTRUMENT CO., INC." "CINCINNATI, OHIO"
Measures 3 1/8" x 3 3/16" x 2 3/16"
These instruments were patented in 1957, this one is patents pending.
The leather case has worn edges and cracks, snaps work well.
Case marked Francis Hankin & Co. LTD These were given out to survey workers, So its most likely the company this particular compass was issued to. (In my opinion)
There is some wear on outer case, Still in working condition from what I can tell. Sold As is.
