Even though these have red hard rubber barrels, normally a quality that commands a premium, these are common enough that I didn’t mind scavenging a clip to complete a rarer model (see http://leadheadpencils.blogspot.com/2016/11/junk-box-nirvana.html).
OK, most of them are common . . .
This one was also in that DC bunch along with all of its “common” cousins:
The short ones are exceedingly difficult to find. Most interesting of all is what you’ll find in a side-by-side comparison of the full sized and midget versions:
That upper metal band is shorter, and the clip on the midget version is a significantly shorter one specially made for this model, complete with a shorter upper tang.
