Been doing some digging around can't seem to nail down how to identify a horseman 4x5 camera. I did find some old threads. I'm thinking of buying one off of eBay and it's listed as an LX but there are so many versions that look absolutely identical how do I tell them apart? From what I understand there are LX, LS, Le, 450 basically they all look the same if you look at them in a photo you can't tell the difference.

I have a guy on eBay that has one for cheap in mint condition I don't think he even knows what it is it's listed as an LX but I doubt that it is.
