Need suggestions of where to look for a Vivitar TX

adapter to fit a Nikon F with an FTN meter. I would like two of them. I have three lens that were given to me but I only have one adapter and it would be much handier to have one for each lens. Any suggestions would be appreciated. Thanks, Grandpaw :)

You can post a free add in the classifieds here. But for somethig that specialized, I'd try searching Ebay and Google.

Thanks for the response. I had tried those and got all excited when I thought I had found one but it was for a Pentax. I did go to a camera show this weekend and purchased a Nikon 55mm 1:1.2 lens for my Nikon F that I have been wanting for the last thirty years. I should be able to some great available light shots with this lens.
