Original 1936 Oil and Gas trade vintage catalog for the AUTHORIZED APPLEMAN BIT SERVICE COMPANY.  Main office and plant were located in Houston, TX.

Manufacturers of the Hunt Retractable Core Barrel.

The core cutter is integral with the bit, as shown. The barrel seats in the bit just above the core cutting teeth, rather than cutting entirely through the bit, and latches under a sleeve near the top of the drill collar. Thus, the barrel itself has no part in cutting the core, but merely receives it, consequently no driving device is necessary period since the barrel is relieved from the strain of cutting the core, a lighter wall is used in a larger core is taken.

Has product images, description and applications to provide product details.
