10k OB means 10k Gold & Ostby and Barton.
The maker Ostby & Barton is out of Providence, RI and the fun history fact is that the maker E.Ostby died on the Titanic in 1911. He was traveling with his young daughter. She did survive. I am a collector of Ostby Items. So if anyone has one they would like to sell. Contact me at Runninbrave@comcast.net or at my Ebay store "Sequoia's 2ND Hand Land" under the username of davids1557.
