Designed for irregular numbering, this machine is capable of consecutive, repeat, duplicate and triplicate numbering. Zeros left of the first digit can be dropped for easier reading (what would normally appear as 000123 reads 123). Dial setting provides quick, easy selection of movements. Stem lock prevents accidental release. One-piece steel wheels wear longer than brass, make sharp, clean impressions. Durable metal frame. Pre-inked and easy to re-ink; no need to remove pad.
