They do exist...sort of. I've got one NOS hanging on the wall. Not surprisingly it's the same one that is shown in your picture. On the internet I've never seen another picture of one, though I know some do (or did) exist, but how many? Luckily I happen to be pretty close with Craig the owner of Sweet Parts, so I gave him a call to ask about them. He said he did produce a few but couldn't recall a number. He said it was only a handful, so it seems likely that the one I have may very well be one of the only ones. I also happen to have the first produced removable face plate sweet stem as well as the testing fixture that has the front half of 3 of them welded on for destructive testing.bump day
