McLean describes Ref. 21 on the patent as

“

a suitably placed perforation for

attachment of the implement or tool to a watch-chain or the like.

”

None of the

three examples above have the attachment at that point. The two gold versions

have a loop with chain link welded on the top and the silver version has a bail

attached where the assembly is riveted together.

A fourth example is marked

“

Security Sterling

”

and

“

Pat.

Apld For.

”

This one is like the

patent drawing and the ring for

attachment to a watch-chain is

located as shown in the patent

drawing.

A fifth example is gold. It does

not have the cigar box nail

remover and the ring for

attachment to a watch-chain is

located at the end of the cap lifter.
