REED 2C Vise PIVOT BASE, vintage

Pivot swivel base for REED 2C big boy vise. Rust but easy to restore this. Please note the irregular surface near one of the mounting tabs.

Be the judge of whether this was a weld. Underside shows NO SIGN of a prior repair.

Might be a casting character mark? Please examine all pics very carefully. Sale for this part only, no other parts included.
