This is a repainted example of Davenport's iconic Square Circle production. 
 
Instructions: None
 
Condition:
Fair, all parts repainted. Paint has wear and chipping and there is some warping to the box, as normally happens. Load chamber has been crudely recovered in paper and had one end blocked up to allow the all parts to be held individually (this could all be redone, but I assume the tube inside needs refinishing for performance, hence being re-papered). Would be a nice restoration project.
