Do you mean just a list of vehicles from WW1? I don't think I recall that. Couldn't you get all that information (what vehicles there were in WW1) from reading Landships, or looking at the index on Landships?
There was a list on the old Landships site of all the tanks used in WWI and links to technical information, drawings, profiles, and photographs. Just below the tank list was another list created by Robert Robinson of all the WWI softskin vehicles small arms,etc where information could be located in books and magazines.
You might be able to dig it out of archive.org. If it hasn't been archived get back to me and I'll see if I can find it in my snapshot of the old Landships.
