Since you do not say where you are this answer has to be broad:  
Microscopic Societies often have ways for selling and buying microscope  
parts, like ads in their journals or web pages. Especially for high value  
brands like Leitz and Zeiss you can get spare parts this way for many  
decades. There are also companies that specialise in used lab equipment.  
And of course a simple web-search for the part number may always turn up  
something.
