Vintage cylindrical brake-lathe boring or cutting bar with a numbered micrometer-style adjustment collar and an articulated cutter-holder head. The head has a central pivot, opposing raised sections and retained side hardware. Ruler photographs indicate an overall length around 5 inches. Thirteen listing stills document the exact item; a duplicate half-second phone clip was excluded. Fit / compatibility: No specific brake-lathe maker or model fit is claimed, and no maker or catalog number is visible. Compare bar length and diameter, collar graduation, head profile, pivot and cutter mounting points to the intended machine. Only the exact pictured item is included.
