I have the original invoice as well as the original assembly instructions. This kit went together as instructed. I built the base and battery box in my wood shop. The engine looks great. I have not been successful at getting it running smoothly. It has good compression and strong spark. Seems that parcel handlers get the drops when items are heavy. I will build a wood crate and secure the engine inside. It weighs approximately 58 pounds. The item “Vaughn Scale model hit-Miss Engine” is in sale since Tuesday, November 19, 2019.
