The parts are beautifully and flawlessly cast in the standard gray resin as all resin detail items from Cutting Edge Modelworks.  The set includes 21 resin parts and a clear film for the gauges.  The detail is crisp and finely detailed.  

As you know the new Ar 234 from Hasegawa is a very nice kit with excellent  detail.  This set permits the modeller to improve upon the good kit cockpit and make it a super detailed masterpiece.  The set even includes the body of the gauges on the back side of the instrument panel.  The seat is delicately detailed and includes molded in resin seatbelts.   This set also includes many tiny little handles that will give plenty of 3 dimensional detail to the cockpit.  The instructions are very comprehensive and include pictures and painting instructions as well as some B&W cockpit photos (not shown in this review).
