See photos. This is the cast aluminum housing / cover for Rockwell / Walker Turner 17-in. drill presses made between about 1961 and 1964 with a left-side depth stop. No cracks or repairs. Sand blasted to bare metal. The small item next to the cover in several photos is a spring-loaded ball bearing oil zerk that should be pressed into the cover (after the cover is painted) as suggested in the 5th photo (it's included in this listing).
