Go to eBay.com and search. I had better luck with "Plath sextant". There are not many for sale at any one time.
In the upper left corner click on "refine", then "more", and then "sold items". It will automatically change the search and show a goodly number of sales.
I see prices from U.S. $200 for a corroded one to over $2000 for a WWII one. C. Plath is one of the more expensive sextants without being an antique. As such there are some fakes offered - search on sextantbook.com.
