I have a picture of an L8A1. Thats as close as it gets. I've heard the Germanyrumor, as well, but suspect that as we'd have first hand reports of them in the hands of collectors by now.
A fellow I know has what he says is an L8, but is unmarked. He said that they made the conversions but didnt engrave them until they were sold and had a buyer ready to take possession. Never heard that anywhere else, before or since. His is an L8 in every respect, but not marked. Lots of questions. I've not been able to make contact with him in the last year, so I don't know if he still has it or not.
My 2 cents.
