After World War II US Army intelligence gathered data and components from the German Wasserfall program. Based on this information General Electric constructed the Hermes A1 rocket which was almost identical to the Wasserfall with the exception of the mid-body fins. Five Hermes A1 rockets were successfully launched at White Sands proving grounds between May 1950 and April 1951.
The Brengun Hermes A1 is molded in medium grey soft plastic with a small photo-etch fret. Flash is minimal the kit offers recessed panel lines however some of these panel lines are partially filled in and will require re-scribing. There is a slight pebbly texture to the plastic typical of many short run plastic kits; a session of sanding with fine sand paper fixes this issue. A couple of the trolley wheels have noticeable sink marks. There is a small decal sheet with markings for three of the test rockets. The instructions are clear and easy to follow.
