The second unit I happened to stumble on is probably one of the most rare Coemar ball effects. In the Venus range, the M4 is very rare and expensive. I now know only two collectors that have a Trisball in the collection. And one of them is me. It comes complete with a dedicated flightcase and basemotor.
Already had some very interesting offers from other collectors to buy this item.. But as all effects in this blog. They are NOT for sale!
