Hi and welcome to the forums. I believe that windows are no longer avalaible for this trailer but you might find some old stock somewhere. I would start watching e-bay and craigslist for a used one from someone who is parting out a trailer.
Use the search tool (upper right corner) and search for argosy window. You should get some results that will provide you with more info. Several forum members have replaced these windows.

Let's have a polishing party: I'll supply the trailer and buffing supplies. BYOB (bring your own buffer)
