No worries, I have too many cameras as it is. That particular camera needs lots of work, as I'm sure you noticed. Plus, it's missing the extension rail and I think you'll find 19.5 inches will not be enough at times.
My question is, why do you want 11x14? If you've not done collodion before, I'd suggest you start smaller; 8x10 or less. Things get trickier as the plate size increases. I shoot 8x10, 11x14 and 14x17 but by far most of my collodion work is 8x10. I really enjoy working this size and there are of course many more 8x10 cameras available for not too much money. Since that camera does not come with a holder, you will have to track one down. If you can find an 11x14 dry plate holder, you can use that for wet plate. Otherwise, you can adapt an 11x14 film holder to hold plates a bit smaller, say 10x12 or so. But any kind of holder this size won't be cheap.
