There is the original <kuid:243828:100205> available on the DLS. Use Download this version to download it. If you have to, open the asset for edit in Explorer. Copy the folder to your desktop and change the KUID to the version you are missing and then import that back in. I do this all the time if I have to get around missing assets like this and it works fine.
