A level apparatus comprising:
- (a) a level housing having a top wall;
- (b) a first bubble tube containing a liquid carried by said level housing;
- (c) a stamping assembly removably connected to said level housing, said stamping assembly comprising:
- (i) a stamp housing;
- (ii) a single elongated stamping member carried by said stamp housing for movement between a first retracted position wherein at least a portion of said stamping member is disposed within an internal chamber and a second position wherein at least a portion of said stamping member extends outwardly from a front wall of said housing;
- and
- (d) operating means carried by said stamp housing for moving said elongated stamping member from said first retracted position to said second position wherein said operating means comprise a plurality of longitudinally spaced push pads carried by said housing and operably associated with said stamping member, each of said push pads being independently movable between a first at rest position and a second operating position wherein said stamping member is moved toward said second position.
