These were made by Joe Ruth ,gone but not forgotten,I provided the castings to him.

I acquired one at an OGCA show about 25 years ago.  It lacked an insert to actually use it, but it was so cool, I had to have it, and in a conversation with Joe Ruth, he confirmed what I had.
Unfortunately, I loaned it to a friend who forgot he had it, and is now unable to find it.  It's a shame too, because that small unit would look so good with my engraved low wall in 25-20 SS, don't you think? 
BTW, Rodney, do you still have the mould for the main body casting part, and if yes, would you be willing to make a run of them?
