Hi Karen,
    The old metal slide racks with a removable handle were made from a 
company called Mercer Glass Works located in NY. The have since went out of 
business. This is why no one can find the racks. 
    Our company now has the racks custom made for us. We carry the 30 and 50 
slide rack with removable handle. As well as a rack to hold 30 - 4" long 
slides.
