The person I bought from lists one from time to time. One is on line on ebay now but not a nice one. He is The camera up now doesn't even have a plate holder with it. It is a 6x8. I like the large dry plate ones.
Yea, I just keep looking on ebay in 8x10 and larger. They are a little rough and often need some minor repairs but for dry plate cameras that get pretty big they are great. He used to offer tripods and extra plate holders.
