As opposed to tossing it?  Of course its worth selling. I
have no idea of what prices it will fetch. If the camera is
an 8x10 and in good condition it is quite usable. Kodak sold
some sizes that are now odd so film is either impossible or
very expensive. These cameras need new backs to be useable.
Also, if the bellows are not free of leaks they have to be
replaced. This costs from $150 to $300 depending on who
makes the bellows.
  5x7 Elwood enlargers are very common. What you have is
really a collection of parts since it would be difficult to
make a working enlarger from it. Elwood had several
variations of their models over the years they were made,
not all parts are compatible. I would offer what you have as
parts.
  Despite the digital revolution LF photography seems to
still be alive and relatively well.

sfrank spake thus:

The camera may be worth something, depending on condition. Others here
can give you more info.

I can tell you my experience with that enlarger: I bought the same
thing, the newer version of the Elwood 5x7 (with metal castings instead
of wood for the lens stage), complete with column ("pole"), glass *and*
lens, for $9. The eBay seller would only sell locally, and I had to pick
it up.

I've sold other "vintage" stuff for pretty good $$, including some 5x7
contact frames, which you might have (wood frames with glass windows).
