Ruby Sidelights

[Colin Morgan]

I have two sidelights (one with a split shell) from a Ruby I used to own.  One has internals identical to those in your photos.  The other has something very similar but about 1/16" (1.5mm) shorter.  As Derek says, there is not much room for the wire, but there must be enough.  There may be varieties of these sidelights with slightly different shell sizes and innards, so a set is needed that works together? (The ones on my current Ruby, from February '37, are Mazak rather than brass and look slightly longer.)
