Vintage combination square head with bubble level, made for machinist and layout work. The photos show a cast iron or steel head with a locking screw and a worn, aged finish; no maker is visible, so it is unidentified by brand.

• Combination square head only; the ruler/blade is not shown.
• Bubble level is present in the body of the head.
• Locking screw is present and visible on the side.
• Cast iron or steel construction with a worn, aged finish.
• Finish shows heavy age wear, rust, pitting, grime, and surface loss.
• No maker's mark, model number, or style number is legible in the photos.

Made for checking square, marking lines, and setting angles in a shop or bench environment, this piece would now suit a vintage tool collection, machinist display, or practical use with a matching ruler blade.
