The inactivity is not for lack of trying. Thought I knew my homebuilds pretty well. There are several that look similar, but nothing quite matches, and a couple that came close I had to rule out as they were US manufactured. Your last clue has really got me...thats if I am interpreting it correctly! You don't have to answer this, but from the look of the design, I'm guessing this kit is in production now?
