The Birmingham proof mark was used post 1813 for proofing black powder barrels. Typically placed below the view mark on the off flat of the breech. We have examined this stamp on Trade Guns by both Barbar, and Sharpe. Due to the large size of this stamp it can only be used on octagon barrels that are 1-1/8" or larger.

The inspector's mark is about .435" wide, about .465" tall, and the tool body is 2-1/2" length, 5/8" diameter, brightly polished steel, hardened to Rc 62 to 65 (as hard as a file). Wrap the body with masking tape to provide a better grip.

Made in the USA, of very hard steel, this tool will give a long life, if used correctly.

Be careful, be safe. If mis-struck, this steel marking punch can become a projectile. Wear safety glasses. Protect your fingers.

Our instructions are included with each tool. Or click the download tab to view, and print these step-by-step instructions as a .pdf file.

Marks on rounded or flat steel surfaces require multiple strikes, in sequence. Marks in wood require only one controlled strike.

No Return, No Refund, No Exchange. Steel marking punches are expendable hardened steel tool bits, with a service life similar to drill bits or hand taps. The value is in the first use. Longevity is under the control of the user. We do not offer a warranty nor a refund for these tools. They are an investment for future use.

Never attempt to mark tempered steel, plated steel, or case-hardened steel with these hand stamps.
