For Airfix or HKCW Saracen
Uparmoured Saracen Mks.6s (with Reverse Cooling systems fitted) in Hong Kong were equipped with push bars to enforce civil unrest. They could be seen both with, and without, the deflector cowling fitted. 
Only four photographs of these bars fitted in N. Ireland have been found - all Mk.2s. Can  be used with the Reverse Cooling Set – CK3568C – seen fitted here.
