I am visiting Los Angeles later this week and next and does anyone know
of any good mechanical music places to see in the area at all.  I'm
also going to be about Las Vegas for a few days if anyone can suggest
anywhere good music-wise to visit there.  All suggestions appreciated.

There are some copy ads for old push-ups at Ian McLaughlin's web site
and the page you want is;-

    http://www.pianola.demon.co.uk/ppadvert.htm

but after do click on the "Back to Home Page" at the foot and explore
the rest of his great site.  There's a complete Fats Waller rollography
there too amongst the pages!

Best Regards
