The numbering sequence is consecutive when the trip lever is depressed, otherwise a constant inscription is marked. Standard wheels have sharp faced characters engraved with 0-9 (inclusive).

Tell-tale characters in the wheel grooves are indicated to show the actual characters in the marking position - particularly helpful when a Numbering Head is used in a Press.
