I bought one of those weddges way back when Hamlin was selling them. I think you may have gotten your information confused though, it was around $25 bucks, not ten.
Back then the HS40 (Tec 33301) slanted intake wasn't available as a repop, only originals were out there. I was fortunate enough to get my hands on a NOS one, and I looked into getting it reproduced. I talked to a couple of foundries and machine shops, and was basically told, with minimum orders required, it would cost north of FIVE GRAND......So I quickly scrapped the project, and got rid of my Rupps.
Since then (I don't know if it was BlackWidow or not, but they seem to be selling the most of them) someone pulled the trigger and had them reproduced. And at $39 bucks each, that's a hell of a bargain for a (once almost impossible) hard part to find. Not to mention, they probably only did one run of them and who knows how long they will last?
