Hello Lars, yes they are the Robinaire retracts. I bought them from someone who waited a mellenium for them! I like them and I paid very little money for them. They are a pretty good scale example as they articulate like the full scale. The Sierra set that is available appear to be better in scale appearance and are more robust but at over $800 US the Robinaire are a better deal.

My set looks pretty awesome with the wheels and tires from Glennis installed. I waited 3 months for my wheels, and it seems that when it comes to scale goodies for this hobby a long wait is to be expected. A 3 year wait as far as Robinaire is outrageous. I would just give Sierra a call. It only took 2 weeks for my tail retract to be made by Sierra-
