Can anyone advise where or who has these for sale? Plastic or Metal? There has to be enough of a demand for someone who has contacts with a machining/fabricating place that some could be massed produced. Probably for a good profit.........

 

there are actually a number of people on the board who have done this and have them for sale.

The down side is that the search function is down so you will have to look through the threads in this forum for the past couple of months to look it up.
