Tom,

Military surplus is a good place to look.  I have purchased some
8-1/2" x 3/4" as well as one 16" x 3/4" port hole from our local 
Army/Navy surplus.  They also had some 10-1/2 x 3/8", if sombody

I have also found a 10-1/2 x 3/4" from a local metal recycler who 
specializes in scraping ships.

I am still looking for the 'dream' glass.

Annother place to look is the Defense Reutilization and Marketing 
Service/Office (DRMS or DRMO).  They have auctions as well as some 
retail stores around the USA.  A friend bought a 'lot' of 12-1/2 x 1" 
port holes at auction and was kind enough to give me one.  He gave the 
rest away years ago for plant stands!!

DRMS is also a good place for motors, bearings and other miscellaneous 
hardware.  A recent auction sold two laboratory interferometers for 
$1200.

DRMS has a homepage at http://www.drms.dla.mil/index.html.

Mike
