Antique wooden Analytical Instrument Box

Where: Uncle Raul's, Jersey City, NJ
Paid : probably $5

Don't know what went in here, but judging by the key, the leather straps, and the craftsmanship of the box it's probably about c.1910-1920's. No manufacturer's marks. There were some metal pins in there. this might have been a holder for a nautical device, probably a sextant like the one meant for  this box   (<-eBay auction to a similar box)
